7-9 Month Old Baby Development & Milestones

Babies at this age have a new understanding of the world. They learn that just because they can’t see mom or dad at a certain time doesn’t mean they don’t exist. So now, your baby may begin to miss you when you’re gone. This can lead to separation anxiety — distress at your departure.

While this might seem like a bad thing, it’s actually very good — and marks an important leap in thinking. Comfort and reassure your baby to help him or her feel loved and secure.

Developmental Milestones

Doctors use certain milestones to tell if a baby is developing as expected. There’s a wide range of what’s considered normal, so some babies gain skills earlier or later than others. Babies who were born prematurely reach milestones later. Always talk with your doctor about your baby’s progress.

How much will my 7- to 9-month-old baby grow?

While all babies may grow at a different rate, the following indicates the average for boys and girls 7 to 9 months of age:

Weight: average gain of 0. 5-1 pound each month; two times the birthweight by 4 to 5 months and three times the birthweight by 1 year
Height: average growth of about ½ inch each month
Head size: average growth of about ¼ inch each month

Babies’ growth begins to slow as the first birthday approaches. Your doctor has measured your baby’s weight, length, and head size (circumference) since birth and put them on a growth chart. This is where to look first if you have questions about your baby’s growth.

When you look at the growth chart with the doctor, compare your baby’s growth with his or her own growth pattern, not with the growth of other babies. As long as your baby’s growth is steady, there’s usually no reason to worry.

If you’re concerned about your baby’s weight or growth, talk with your doctor, who might ask:

Has your baby been sick? A couple days of not eating, especially if combined with vomiting or diarrhea, can lead to weight loss. The weight will come back when your little one feels better.
Is your baby on the move? Crawling, cruising, and walking will burn calories, so weight gain might be less with this new mobility.
Is your baby more interested in playing peek-a-boo or dropping the spoon on the floor than eating? The world is a fascinating place, and your baby is learning new things every day. Try not to distract your baby during mealtime. Also watch for signs that your little one has eaten enough.
Are you introducing the right kinds of foods? As your baby gets better at eating, pay more attention to the texture and types of foods you serve. If your child isn’t interested in puréed baby foods, try soft table foods and finger foods that are safe and fun.
Is your baby drinking enough breastmilk or formula still? Liquid volumes decrease as solid food volumes increase. However, it is important your baby continues to drink 20-28 ounces of breastmilk or formula a day to have enough calories to grow.

Can babies gain too much weight?

A few babies and toddlers are overweight. In those cases, advice from the baby’s doctor can help, such as:

Never skip feedings. Watch for signs from your baby that he or she is full. Make sure your baby’s calories come from nutritious sources — like fruits, vegetables and fortified cereals. Breast milk or formula should still be the main source of nourishment in the first year of life.
Play with your baby and encourage physical activity. Make sure that your little one has a safe space to move around in. Limit the time spent in car seats, strollers and playpens.
One of the best things you can do for your baby is to eat well and be physically active yourself. Your baby has a better chance of growing up fit if good health habits are part of the family’s way of life. You’ll be a good role model — and have the energy to keep up with your little one.

What can my 7- to 9-month-old baby do at this age?

Babies are rapidly developing their physical abilities at this age. They become mobile for the first time and safety in the home becomes an important issue. While babies may progress at different rates, the following are some of the common milestones your baby may reach in this age group:

Rolls over easily from front to back and back to front
Sits leaning forward on hands at first, then unsupported
Bounces when supported to stand
Gets on hands and feet and rocks back and forth
May creep, scoot, crawl – backward first, then forward (some babies skip crawling!)
Begins to pull up to stand
Reaches for and grasps objects using their whole hand
Bangs toy on table
Can hold an object in each hand
May hold a bottle
Plays peek-a-boo
Grasps object with thumb and finger by 8 to 9 months
Begins teething, usually starting with the two center front teeth in the lower jaw, then the two center front teeth in the upper jaw
Learns to drink from cup
Puts everything into mouth
Naps are usually twice, sometimes three times a day, for one to two hours each (on average)
May begin to awaken during the night and cry

Why is touch important for development at 7- to 9-months?

Your baby is getting around more independently as he or she learns to scoot, crawl, or walk. This means your baby can go and touch the things he or she wants to touch. Let your baby explore the textures and surfaces of your home and yard. Babies explore with their hands first and then their mouths. Make sure there are no hot, sharp, or other dangerous things that can hurt your baby.

How long should my 7- to 9-month-old baby sleep?

Most babies this age should sleep 12-14 hours per day, including a stretch of 9-12 hours at night. However, sleep problems are common in the second half of a baby’s first year. Some babies may experience separation anxiety and cry when being put to sleep or when they wake up in the middle of the night. Sleep regressions are common with leaps in development. Sleep regression is when babies who have been sleeping well have difficulty going to sleep, waking up in the middle of the night or not napping.

Check out our 9-month sleep regression guide for more info.

How can I help increase my 7- to 9-month-old baby’s development and emotional security?

Consider the following as ways to foster the emotional security of your baby:

Give your baby safe toys that make noises when shaken or hit.
Play in front of a mirror, calling your baby by name and pointing to your baby’s reflection in the mirror.
When talking to your baby, pause and wait for him or her to respond just as when talking with an adult.
Play pat-a-cake and peek-a-boo.
Clap and wave your hands.
Name common objects when shown to your baby.
Make a variety of sounds with your mouth and tone of voice. Sing songs.
Repeat and expand the sounds your baby makes, such as “ma-ma” when he or she says “ma.”
Show picture books and read stories to your baby every day.
Give your baby toys with objects or knobs to push, poke or turn.
Give your baby toys that stack or nest and show him or her how they work.
Build a tower with your baby and show him or her how to knock it down.
Establish a routine for bath and bedtime.

Communication and Sensory Milestones

What can a 7- to 9-month-old baby say?

It is very exciting for parents to watch their babies become social beings that can interact with others. While every baby develops speech at his or her own rate, the following are some of the common milestones in this age group:

Makes two syllable sounds (ma-ma, da-da)
Makes several different vowel sounds, especially “o” and “u”
Repeats tones or sounds made by others

What can a 7- to 9-month-old baby understand?

A baby’s awareness of people and surroundings increases during this time. While babies may progress at different rates, the following are some of the common milestones in this age group:

Responds to own name and “no”
Pays attention to conversation
Appears to understand some words (such as “eat”)
Prefers mother over others
Enjoys seeing self in mirror
Responds to changes in emotions of others
Is afraid of strangers
Shows interest in and dislike of foods
Makes attention-getting sounds, such as a cough or snort
Begins to understand object permanence and can uncover a toy after seeing it covered or watch a spoon as it falls off their high chair
May follow one-step commands with a sign to demonstrate (such as, “get the ball” while parent points to ball)
Can start to learn basic sign language to communicate

What can a 7- to 9-month-old baby see?

Your baby’s eyesight has been maturing for many months, and he or she is able to see quite well near and far and even focus on quickly moving objects. Your baby’s motor skills are now working together with eyesight (hand–eye coordination), and it’s likely that he or she can spot a toy across the room, focus on it, move to it, pick it up, and explore it in lots of ways.

Familiar and loving faces are still your baby’s favorite things to look at, but he or she also may enjoy looking at pictures in books, especially familiar images. Your baby may love objects with parts or pieces that move and will spend lots of time staring at and manipulating these things, trying to figure out how or why they work. Take your baby with you to see new and interesting places. Point out the sights and label them by name.

What can a 7- to 9-month-old baby hear?

As your baby is grows, their hearing develops, and they can begin to listen and understand more. They can begin turning to the direction where sounds came from. Babies at this age can also start to recognize words for common items.

What can a 7- to 9-month-old baby taste and smell?

By this age, your baby is developing food preferences. Keep offering foods with a variety of tastes and smells. Don’t give up if he or she doesn’t take to it right away. It can take over ten times before a baby learns to try a new food.

Explore the sense of smell with your baby, too. Use scents to help your baby understand the world further. A trip outside can provide a wide variety, from the sweet scent of flowers to the distinctive smell of just-cut grass.

When to Talk to Your Doctor

Every baby develops at his or her own pace, but if you notice anything that concerns you — however small — share it with your doctor. Talk to your doctor if your baby:

Shows no reaction when you leave the room
Cannot roll onto the belly
Hasn’t lost newborn reflexes, such as the startle reflex
Cannot sit upright without support
Does not respond to their name
If you notice that your baby has lost skills he or she once had or shows weakness on one side of the body

7-month-old baby: Development, Milestones & Growth

Your 7-month-old is starting to see and understand so much more about the world. They can now see in full color, make out things that are far away, and track objects with their eyes more easily. Separation anxiety often starts now, so don't be surprised if your baby cries and clings to you when you're heading out alone. Here's what else is in store for both of you this month.

Your 7-month-old is ready to explore, and now that they can move on their own, there may be no stopping your little one. (Make sure you've done your babyproofing!)

For some parents, these developments can be bittersweet. Your baby is growing up, and it might seem like they're moving away from you as fast as they can. But take heart – there are still a lot of snuggles in your future.

In fact, as your baby becomes more physically independent, they'll need your love and support more than ever. Navigating a new world is exciting – and scary at times. As a parent, you get to enjoy watching your 7-month-old make new discoveries almost every day and encourage their efforts. Here's what to look forward to this month.

Your baby's development

Your baby is most likely trying to move however they can – rolling both ways, pulling up into a seated position, even trying to crawl.

Once your baby can sit well without support, they'll figure out how to get on their hands and knees and rock back and forth. Then they'll figure out how to move forward and backward by pushing off with their knees. Not all babies crawl the standard way – some prefer to push themselves around on their bellies or scoot on their behinds. And some babies never crawl and use other methods to get around instead.

Your 7-month-old is also developing emotionally, and this may lead to the beginning of separation anxiety this month. Younger babies don't understand object permanence, so when they can't see an object, it's like it doesn't exist. (Literally, it's out of sight, out of mind!) Older babies begin to understand that things and people exist even when they're not present – which makes them more disturbed when you leave. (Because why aren't you coming back already?)

Separation anxiety can make bedtimes more difficult, and can have you both in tears when you're leaving your child to run an errand or go to work. It may pop up repeatedly for your child during the baby and toddler years, but the good news is that separation anxiety is a sign of normal and healthy emotional development.

7-month-old milestones

Here are some of the milestones that your 7-month-old baby may reach:

Rolling over. Your baby may have mastered rolling from front to back and back to front. They may even use rolling as their primary way of getting around!
Sitting up. This month your baby may be sitting up without any help. If your 7-month-old still topples over now and then, use pillows to prop them up (and make sure to supervise).
Better vision. Your baby's eyesight has improved, and they can now track moving objects more easily and see things that are farther away. Plus, your 7-month-old can now see in full color!
Hand coordination. Your baby is still working on hand coordination, and can probably hold larger items, like toys and blocks, and move them from hand to hand. But your baby doesn't yet have the dexterity to pick up small objects like peas. (The pincer grasp – using the finger and thumb to precisely pick up tiny things – won't develop until they're around 9 months old.) You may notice that your baby using a "raking grasp" to move small objects closer to them. Your baby can also most likely reach with just one hand now.
Understanding language. Your baby understands language better – including what your tone conveys as well as certain words – like "no" and their name. At 7 months old, your baby is becoming attuned to your tone of voice, and may react with joy when you sound happy and tears if you sound angry. Your baby can use their voice to express joy or displeasure, and can babble to you.
Social play. Interacting with you and others is important to your baby. Have fun with classic games like peekaboo and itsy-bitsy spider, or explore books and toys together.
Supporting their weight. Your baby may be able to support their weight with their legs when you hold them under the arms. They're getting ready to learn how to stand on their own!

Although babies follow fairly predictable patterns of development, all babies are different. It's a good idea to be aware of milestones and tell your baby's care provider if you have any concerns about a developmental delay. But keep in mind that some babies just need a bit more time to learn skills and hit milestones.

7-month-old weight and length

How much should a 7-month-old weigh? At this age, babies can vary quite a bit. Here are some averages:

Baby boys

Average weight for a 7-month-old: 18 pounds 5 ounces
Average length for a 7-month-old: 27 1/4 inches

Baby girls

Average weight for a 7-month-old: 16 pounds 12 ounces
Average length for a 7-month-old: 26 1/2 inches

Factors like how active your baby is and how much they're eating will affect their weight. Also, from 6 to 9 months, your baby's growth rate will naturally slow down. That's partly because your active baby is expending more energy, but it's also just how babies grow. If you have any concerns about your baby's weight or growth, be sure to talk to their provider.

7-month-old feeding

Is your baby liking baby food? At 7 months old, some babies are still trying a few teaspoons of a one-ingredient food (like a pureed fruit, veggie, or meat) once a day, while others are ready for several meals. Either way, it's fine – see our age-by-age guide to feeding your baby for more details.

As your baby gets more comfortable with eating, you can start to add a variety of foods and increase the frequency of meals. Try pureed bananas, pears, applesauce, peaches, avocado, carrots, squash, or sweet potato. You can also try pureed or mashed chicken, pork, beef, tofu, and beans; small amounts of soft pasteurized cheese, cottage cheese, or unsweetened yogurt; iron-fortified cereal; or small pieces of bread and crackers.

Offer a wide range of flavors, but introduce new foods one at a time and wait three to five days, if possible, before giving another new food. This can help you identify any food allergies. It's also a good idea to write down the foods your baby samples. If they have an adverse reaction, a food log will make it easier to pinpoint the cause.

You don't have to put off giving allergenic foods such as eggs or soy. In fact, there's some evidence that introducing these early can actually help prevent allergies. But if your baby is at high risk for food allergies, talk to your baby's healthcare provider first.

So how much does a 7-month-old eat? Amounts of solid food will vary, but most of your baby's nutrition still comes from formula or breast milk. You can expect your baby to have 24 to 32 ounces of formula or breast milk a day.

Your 7-month-old's feeding times may space out more – to three to five bottles or nursing sessions a day. If your baby is bottle-fed, they will drink around 6 to 8 ounces per bottle. Also, if you want, you can introduce your baby to a sippy cup or straw cup by putting breast milk, formula, or a small amount (4 ounces or less) of water in the cup for your baby to try.

If you're nursing, you can continue to nurse on demand if you and your baby want to. Your baby may want to nurse for comfort even when they're not necessarily hungry, and that's okay.

One more note about feeding: As your baby starts to eat solids, their poop may become firmer, change color, and smell much worse. This is normal. But if your baby's poop is extremely loose, watery, or full of mucus, talk to your baby's provider.

7-month-old sleep

At 7 months old, your baby will still need between 12 and 16 hours of sleep (including naps) every 24 hours. That might look like 10 hours at night and 4 hours during the day, taken in morning and afternoon naps. But there's a big range of normal at this age.

An overtired baby may actually resist sleep, so do your best to stay on track with your baby's sleep schedule or usual routines.

Some babies may have a 7-month sleep regression due to separation anxiety or other developmental changes. They may be so busy working on new skills at bedtime that they don't want to go to sleep, or may wake up in the middle of the night to practice them! Sticking with the good sleep habits you've been working on with your baby can help you both get through a sleep regression.

By 7 months old, most babies have settled into a more predictable sleep schedule and are sleeping through the night. However, some babies still wake up at night and want a feeding. If you enjoy nursing or giving a bottle to your baby at night, there's no reason to stop. But if you're exhausted, it's a good time to investigate baby sleep training and night weaning.

It's very important to make sure your baby is still sleeping safely. Your 7-month-old can get around now, which means you'll want to be sure to do things like:

Make sure your baby's crib is safe. You may need to move the mattress down so your baby can't fall out.
Say goodbye to the bassinet if you haven't yet. A bassinet isn't safe once your baby is between 4 and 6 months old, or starts pushing up on their hands and knees.
Continue to avoid crib bumpers, stuffed animals, quilts, loose blankets, and pillows in your baby's crib. Don't let your baby sleep with these soft objects until age 1.
Continue to share a room (but not a bed) with your baby. The American Academy of Pediatrics (AAP) recommends that your baby sleep in your room – but not in your bed – at night for at least the first six months, and ideally for the first year.

Your baby's health

Your baby doesn't have a well-baby checkup this month – the next one will be at 9 months. However, you can always call your provider if you have any concerns about your baby's health.

If your baby missed or fell behind on any vaccines, or didn't receive the flu vaccine at their last checkup (and it's flu season), you can schedule a vaccine-only visit so your baby can get their shots.

Although it's still early, some babies may begin teething this month. The signs of teething include drooling, irritability, swollen gums, sleep problems, refusing to eat, and rubbing their face and ears.
