Thumb sucking in womb
Fetal Development Milestones - Care Net Pregnancy of Southern Maryland
1 day to 7 week fetal development
A new individual receives 23 chromosomes from each parent. He or she is truly a unique individual human being, never to be repeated. A new person has been created, who at this stage is a tiny living organism weighing only 15 ten-millionth of a gram. Life begins.
First day of new life: The first cell divides into two, the two into four, and so on. Each of these new cells divides again and again as they travel toward the womb in search of a protected place to grow.
18 days from conception, heart begins to beat, with the unborn baby’s own blood.
28 days from conception a unborn baby has eyes, ears, and even a tongue!
28 days from conception: Muscles are developing along the future spine. Arms and legs are budding.
30 days: Unborn baby has grown 10,000 times to 6-7mm (1/4”) long. Brain has human proportions. Blood flows in veins.
42 days: Skeleton is formed. Brain coordinates movement of muscles and organs. Reflex responses have begun.
42 days: Brain waves can be detected, the jaw forms, including teeth and taste buds. The unborn baby begins to swallow amniotic fluid. Fingers and toes are developing.
45 days from conception: The unborn baby is making body movements, a full 12 weeks before the mother may notice such stirrings. By seven weeks the chest and abdomen are fully formed. Swimming with a natural swimmer’s stroke in the amniotic fluid, the unborn baby now looks like a miniature human infant.
44-45 days: Buds of milk teeth appear, and the unborn baby’s facial muscles develop. Eyelids begin to form, protecting the developing eyes. Elbows take shape. Internal organs are present, but immature. 99% of muscles are present, each with its own nerve supply.
52 Days: Spontaneous movement begins. The unborn baby then develops a whole collection of moves over the next 4 weeks including hiccuping, frowning, squinting, furrowing the brow, pursing the lips, moving individual arms and legs, head turning, touching his/her face, breathing (without air), stretching, opening the mouth, yawning and sucking.
8-10 week fetal development
8 Weeks: Now a small-scale unborn baby, at approximately 3 cm (1 1/8”) and weighing a gram (1/30gth oz.), yet well proportioned. Every organ is present. Unborn baby’s heartbeat is steady. Stomach produces digestive juices. Liver makes blood cells. Kidneys begin to function. Taste buds are forming.
8 ½ Weeks: The unborn baby’s fingerprints are being engraved. Eyelids and palms of hands are sensitive to touch.
8- 8 ½ Weeks: Of the 4500 structures in the adult body, 4000 are now present in the unborn baby. The skeleton of the arms and legs and the spine begins to stiffen as bone cells are added.
9 Weeks from conception: The unborn baby will bend fingers around an object placed in his/her palm. Unique fingerprints appear. Thumb sucking may occur.
10 Weeks: The unborn baby’s body is sensitive to touch. He/she squints, swallows puckers up brow and frowns. Eyelids, fingerprints and even fingernails are evident.
11 week fetal development
11 Weeks: The unborn now “practices” breathing, since he/she will have to breathe air immediately after birth. Unborn baby urinates, and stomach muscles can now contract. Vocal chords and taste buds form. Facial expressions and even smiles are evident.
12-17 week fetal development
12 Weeks: Though too small to be felt by the mother, the unborn baby reaches peak frequency of movement during the third month. The unborn baby’s sex can be visually determined, and the unborn baby’s eyes, ears and face begin to display distinctive characteristics. He/she can kick, turn feet, curl and fan toes, make a fist, move thumbs, bend wrists, turn head, open mouth and press lips tightly together.
12 Weeks: The unborn baby is now about 3 inches long, weighing approximately 2 ounces. Fine hair begins to grow on his/her upper lip, chin and eyebrows. The unborn baby swallows and responds to skin stimulations.
13 Weeks: The unborn baby is about 3 inches long, weighing approximately 3 ounces. His/her facial expressions may resemble the parents. The unborn baby is active, but the unborn baby is too small for mother to feel anything.
14 Weeks from conception: At this age, the heart pumps several quarts of blood through the body every day. The unborn baby’s eyebrows have formed and eye movement can be detected.
15 Weeks: In the growth development of the unborn baby, a wild production of nerve cells begins and continues for a month. A second surge will occur at 25 weeks. By now the unborn baby also has an adult’s taste buds.
4 Months: The unborn baby is now only 5 ½ inches long, weighing approximately 5 ounces. He/she is actively moving about inside the safety of the womb. The unborn baby turns, kicks and even somersaults – some of which can now be felt by the mother.
4 Months: Bone marrow is now beginning to form and the unborn baby’s heart is pumping 25 quarts of blood a day.
18-19 week fetal development
4 1/2 Months from conception: Still very small (less than 8 inches in length), the unborn baby can have dream (REM) sleep. Nostrils and toenails become visible.
4 1/2 Months: The unborn baby’s ears are functioning by the end of the 4th month and he/she hears the mother’s heartbeat, as well as external noises like music. The unborn baby is also able to experience pain. Life-saving surgery has been successfully performed on babies at this age.
18-20 Weeks: The unborn baby has grown in size approximately 7 ½ inches long and 14 ounces in weight. His/her movements can now be felt by the mother, including the unborn baby’s hiccups.
20-26 week fetal development
5 Months: Each side of the brain now has a billion nerve cells. If a sound is especially loud, the unborn baby may jump in reaction to it. Thumb-sucking has been observed during the 5th month.
5-6 Months: The unborn baby practices breathing by inhaling amniotic fluid into its developing lungs. The unborn baby will increase seven times in weight and nearly double in height.
6 Months from conception: Fine hair grows on eyebrows and head. Eyelash fringe appears. The unborn baby’s weight is about 640g (22 oz.), height 23cm (9”). Babies born at this age have survived.
27-32 week fetal development
25-28 Weeks from conception: The unborn baby can recognize his/her mother’s voice. The unborn baby is using four of the five senses (vision, hearing, taste, and touch), opens and closes his eyes, and knows the difference between waking and sleeping, and can relate to the moods of the mother.
8 Months: The unborn baby’s skin becomes pink and smooth. The pupils of the eye respond to light.
8 Months: The unborn baby’s weight increases by 1 kg. (over two pounds) and his/her living quarters inside the mother’s womb are becoming cramped.
8 Months: The unborn baby’s fingernails reach to the tip of the finger. The skin begins to thicken, with a layer of fat stored underneath for insulation and nourishment.
8 Months from conception: The unborn baby swallows a gallon of amniotic fluid each day and often hiccups. Though movement is limited, due to the cramped quarters the unborn baby’s kicks are stronger, and mother may be able to feel an elbow or heel against her abdomen.
33+ week fetal development
9 Months (33-40 Weeks) from conception: The unborn baby gains about one-half pound per week as she/he prepares for birth. The bones in the unborn baby’s head are soft and flexible to more easily mold for the journey down the birth canal.
9 Months (33-40Weeks): The unborn baby triggers labor and birth occurs, an average of 264-270 days after conception. Of the 45 generations of cell divisions before adulthood, 41 have already taken place. Only four more come before adolescence. Ninety percent of a person’s development happens in the womb.

Thumb sucking in infants is common, often starting before birth. In most cases, babies and toddlers stop sucking their thumb by themselves. However, thumb sucking may cause problems with children's developing teeth and jaws if it continues while their adult teeth are coming through.
Why do babies and children suck their thumb?
In their first year, up to 1 in 3 of babies suck their thumb. Sucking is a natural reflex in newborns that helps them to feed. In some babies and children this reflex can develop into thumb sucking or sucking other fingers, which is a normal, comforting behaviour for young children. It can help them self-soothe, feel secure and help them go to sleep.
Most toddlers naturally stop sucking their thumb between 2 and 4 years old and by the age of 8, less than 1 in 20 children sucks their thumb.
Is thumb sucking bad for teeth?
Many children who suck their thumb go on to have normal teeth. Whether thumb sucking causes a problem depends on the child’s growth development, how often they suck their thumb, the angle of their thumb in the mouth, and how hard they suck.
Some experts believe that it’s not a problem unless the child is still sucking their thumb once permanent teeth (adult teeth) start to appear.
Problems caused by thumb sucking can include:
- the child’s upper jaw being pushed out further from their face
- upper front teeth being pushed upwards and out, commonly called an ‘overbite’
- tipped back lower front teeth
- a gap between the child’s upper and lower teeth
- not being able to bite the front teeth together
- the palate (roof of the mouth) becoming pushed up and narrow
- speech being affected, such as forming a lisp
- the tongue not being in a normal position in the mouth
How to stop your child sucking their thumb
Remember, most children will stop sucking their thumb by themselves by the time they are 4 years old. Others will stop when they get to school and find out that other children there are not sucking their thumb.
Positive reinforcement is the best way to help your child to stop thumb sucking, as well as support, encouragement and reminders. Noticing when they haven't been sucking their thumb, and pointing out how 'grown up' they are, is a way to be positive. It also becomes easier when the child realises that they want to stop sucking their thumb.
Here are some strategies for helping your child to stop thumb sucking:
- Gently remind your child regularly to take their thumb out of their mouth, and when they do, offer hugs and praise. You may also like to create a private signal if you are with other people, to prevent your child being embarrassed about the reminder.
- Record their thumb sucking on a calendar, with rewards or stickers when they reduce or stop the behaviour.
- At night, dress your child in a large pyjama top with the arm ends sewn up, or use gloves, mittens or a thumb guard as a barrier.
- Look for what is triggering the thumb sucking. For example, if stress or fear causes your child to put their thumb in their mouth, help them reduce this fear in other ways, such as with a hug or comforting words. You could also give them a soft toy they can squeeze.
Thumb sucking is a habit which may take some time to stop, so try to be patient and positive while helping your child. Encourage them to want to stop themselves and don’t nag them in a negative way, as this can make the habit worse.
If the habit continues after they start school, you may like to discuss it with your child’s dentist or orthodontist. It’s best to wait until this age because your child needs to be old enough to understand, and accept responsibility to break the habit.
These strategies may also help your child to stop using a dummy.

How to wean a child from sucking his thumb: advice from a pediatrician and a dentist
Why does a child suck his thumb
As Irina Meshcheryakova, a pediatrician at the SM-Clinic in St. Petersburg, explained to Gazeta.Ru, the reflex process of sucking appears in children even in the womb. Often, with an ultrasound examination, it is possible to see that the child is sucking on his fingers.
After the birth of , baby may suck her thumb to satisfy the sucking reflex - especially if the mother for some reason stops breastfeeding too early and transfers the baby to artificial feeding. Also, most children put their fingers in their mouths for the purpose of self-soothing.
“If the child is anxious, then this activity allows him to feel the comfort and security that he receives at the mother’s breast,” explains the pediatrician.
The habit of thumb sucking can be explained by problems in the emotional sphere, for example, when a child lacks acceptance, care and love.
Why is the habit of sucking fingers dangerous? from the gastrointestinal tract. And, of course, do not forget that the oral cavity is the "entrance gate" for infection. Unwashed hands that a child constantly puts into his mouth are the cause of many infectious diseases.”
In addition, the doctor warned that you need to pay attention to how the child holds his fingers in his mouth: loosely or presses on the gum. In the second case, bite changes, the formation of a gap between the upper and lower front teeth, forward tilt of the front teeth, narrowing of the upper jaw are possible.
How does breastfeeding affect the bite? and head and body position. The muscles that help develop the jaws correctly are involved, in particular the position of the lower jaw.
Thanks to this, the correct position of the articular head and articular surface is formed.Early transition of the baby to artificial feeding can develop in him the habit of sucking his fingers - in this way the baby will try to get closer to the sensations that he experienced at the mother's breast. However, this is fraught with the formation of an incorrect bite.

Formation of malocclusion (open bite)
Vladimir Losev warns parents that bite deformity can be caused not only by the baby's thumb sucking habit, but also by using the wrong nipple when switching to artificial feeding. The situation is aggravated when the child lies not on its side, but on its back - in this position, other muscle groups are involved (in contrast to what happens during natural breastfeeding), which leads to an incorrect formation of the lower jaw.
“This leads to a decrease in the volume of the lower jaw, it narrows - accordingly, there is a decrease in the volume of the oral cavity, there is little room left for the tongue, it begins to strive outward. All this causes the front teeth to be pushed out - thus an open bite is formed, ”explains the doctor.
The dentist also noted that there are special anatomical nipples that are designed so that the child does not experience bite changes and is formed correctly, as during breastfeeding.
“They must be used from six months to a year. During this period, the formation of the joint takes place, ”explains Vladimir Losev.
It is also important to wean the child from thumb sucking in time.

In the first year of life, the habit of sucking fingers is not so dangerous, however, the sooner the child gets rid of it, the less unpleasant consequences it will have, explains Irina Meshcheryakova.
“It is believed that at the age of three or four this habit should disappear on its own and without any special consequences. The main thing is that the child should stop sucking his thumb before the age of six or seven, when the milk teeth are replaced by permanent ones. If the habit persisted at an older age and permanent teeth fell under the influence, then you need to contact an orthodontist, ”comments the pediatrician.
How to wean a child from thumb sucking
If a small child constantly puts his fingers in his mouth, then the correct approach to feeding will help to get rid of this habit.
“If the baby sucks his fingers between breastfeeds, it is worth increasing the time of the meal. If the child is artificially fed, the diameter of the hole in the nipple should be reduced so that the feeding process becomes longer,” recommends Irina Meshcheryakova.
The pediatrician emphasizes that in no case should a child be punished for a bad habit. Parents who try to wean their child from sucking fingers with mustard are also making a mistake.

“You should not try to smear strong-smelling substances, bitter varnish or savory sauces on a child's fingers - this will not lead to the desired result. The baby can be put on mittens at night so that he cannot suck his finger in his sleep, and during the day gently remove the hands from his mouth. You need to control this process calmly and methodically. But no more than that, since the stress of screaming or punishment, on the contrary, will lead to the fact that the baby will suck his fingers even more - because this process calms, ”warns Dr. Meshcheryakova.
If you can't get rid of this habit, then you should think about the psychological state of the child. Perhaps a traumatic situation persists, or the child simply does not know what to do with himself. In both cases, everything is in the hands of the parents.

Irina Meshcheryakova offers parents some simple rules for communicating with their children:
· devote more time to your child;
· do not allow manifestations of aggression or negative emotions in the presence of a child;
Praise him often for all his achievements, including the absence of the habit of sucking his thumb.
If the above measures do not give the desired effect, you should contact the orthodontist, who will prescribe the wearing of plates with limiters.
In case the matter is in the psychological state of the son or daughter, a child psychologist will help. However, the specialist should work not only with the child, but also with the parents, because in this case the psychological atmosphere in the family depends on adults.
9 baby abilities before birth
The baby in his mother's stomach spends time quite actively and fruitfully: he sucks his finger, hiccups, pisses, plays with the umbilical cord - in a word, he has a lot to do!
Legion Media
I remember when I was pregnant I wanted so much to see what my son was doing in my tummy! One of the assumptions was obvious: he plays football there or trains to be a sumo wrestler, because he kicked and pushed mercilessly. Sometimes the son seemed to freeze and listen to what was happening outside his temporary home. Are you all right there, parents? But much more often he gave a good beating to my ribs. His heels worked non-stop.
1 Moves
Already at the very beginning of pregnancy, around 9-10 weeks, the baby begins to move. But he is still so tiny that mommy simply does not feel his movements. A lot of activity in the crumbs begins from about the 12th to the 24th week. It is at this time that the child still has enough space in the mother's tummy to "turn around" to the fullest. The peanut plays with the umbilical cord, bends and unbends the arms and legs, sucks his thumb and generally spins inside his mother like a top. In the last weeks of pregnancy, the baby makes already deliberate movements: she rubs her eyes, touches her face. But there is less and less room to maneuver. Therefore, the little one is diligently moving his arms and legs - “pushing”.

2 Hiccups
In the second half of pregnancy, starting at about the 27th week, the baby sometimes . .. hiccups. The baby moves not only the arms and legs, but also the diaphragm. Diaphragm movements can be detected on ultrasound even in the first trimester. When a convulsive contraction of the diaphragm occurs, the baby hiccups. Some experts are inclined to believe that hiccups are a kind of training for independent breathing. According to another version, this is the result of the fact that the little one swallowed amniotic fluid. In addition, the involuntary process of diaphragm contraction can also be considered as a kind of massage that contributes to the normal development of the internal organs of the crumbs. Scientists have not yet come to a consensus.
3 Reacts to light
At the 6-7th month of pregnancy, the baby reacts to bright light, and this despite the fact that the function of vision in the baby is not in demand until the very moment of birth. And yet, even while in the uterus, the baby sees! If you direct a bright source of light, such as a lamp, at the belly of a pregnant woman, you can see how the baby grimace (grimaces) with displeasure, closes his eyelids (squints), or even turns his head. Some babies, especially in the last trimester, really dislike the light and even turn or turn over so as to remain in a comfortable twilight.

4 Stretches and yawns
A toddler can yawn as early as the 10th week of pregnancy. From about the 24th week, yawning becomes his constant companion, and the baby yawns several times a day. But by the end of intrauterine development, it almost stops. The baby, when he yawns, can reflexively stretch, as do adults. By the way, scientists still do not know the answer to such a simple question: why do we yawn at all? If we do this regularly throughout our lives, does it mean that we still need it for something? It is believed that yawning is responsible for the thermoregulation of our body, and at the time of embryonic development, the baby trains jaw movements in this way.
5 Teases
By the 36th week, almost before the birth, the baby already has an almost full range of emotions. If a bright source of light is directed at the mother's tummy, the baby may frown, close his eyes and turn away. If mommy has just eaten something sweet or already loved by the baby, then he smiles. Sometimes the child even sticks out his tongue and makes a face. Of course, he does not tease, grimaces and expresses joy in our understanding. Just like that, he grows and hones all the shades of emotions.
6 Thumb sucking and drinking amniotic fluid
Starting at about 11 weeks, baby sucks on his thumb. The longer the gestation period, the more time he devotes to his favorite pastime - thumb sucking. Some experts draw parallels between which hand the baby sucks his thumb on before birth and who he then grows up to be - left-handed or right-handed. From about the 12th week of pregnancy, the baby begins to swallow amniotic fluid. This contributes to the development of his digestive system. When his taste buds are already sufficiently developed, the baby can even "taste" the food that mom eats and appreciate it. They say that it is during this period that the taste preferences of the child are laid. At the end of the first trimester, when the embryo receives the status of a fetus, it is already able to excrete urine.
7 Plays with the umbilical cord and claps his hands
The little one has a favorite toy even before he is born. It's... the umbilical cord. Yes, yes, the very umbilical cord through which the baby receives nutrition. The baby periodically reaches the umbilical cord and plays with this "rope", although of course so far these are just involuntary movements - harbingers of a grasping reflex. The same can be said about the baby's ability to clap. His exercises and patty games are clearly visible on ultrasound. So your child trains motor skills, which will be useful to him in the future. Mommy should not worry if she feels pretty strong pushes of the little one. A moderately active baby in the tummy is very good. So everything is going as it should.

8 Listens to the mother's heartbeat and other sounds
From the second half of pregnancy, the baby already hears - that is, it reacts to sound impulses and responds to them with a rapid heartbeat or the movement of tiny arms and body. By the 26th week, he is able to distinguish sounds. Hearing plays a very important role in the study of the outside world. That is why future parents are advised to talk to the "tummy" so that the baby gradually gets used to the timbre of the voices of mom and dad. Classical music has a positive effect on the development of the baby. In addition to the sounds of the “outer” world, the baby perfectly hears the inner world: the mother’s heart is beating, the blood is roaring, the intestines are rumbling.
9 Sleeping
In the second trimester of pregnancy, the baby sets its own, special rhythm of sleep and wakefulness, which, as a rule, not only does not coincide with the mother's regimen, but goes against it. When mom is sleeping, the baby is awake. And vice versa. Approximately 90% of the time the baby sleeps. Take advantage of this to do household chores and relax. The fast phase helps brain development. By the way, many mothers most often feel how the baby is active and pushing at night, when they are going to sleep, and at this very moment the baby decides to tell her mother: “Good morning!”.
