10 Month Old Baby Milestones And Development – New Parents Guide


Your little one just turned 10 months old and all of a sudden, life’s gotten pretty chaotic! He is always on the move, crawling to places and touching objects he shouldn’t. His mission to seek and destroy seems to be at its peak now, so make sure you are keeping a watchful eye on him. 

At this age, the baby is also interacting more with people, showing off his newfound skills every chance he gets. 

So what’s next? Read on to find out all the transformations your little daredevil will undergo as he marks the 10 month old milestones. 

What You Should Know

  • 10 month olds love music. Turn it on and your baby will bop and bounce along to the rhythm.
  • Baby is a bit of a scientist now, curious to explore the world around him. Let him do his thing but also learn to say “No!”
  • Secure toys to your infant’s car seat while driving; you don’t want a frustrated, whiny tot throwing toys your way or at your windscreen.
  • Schedule your baby’s 12 month checkup.

The Most Adorable 10 Month Old Milestones

One of the puzzles of your 10 month baby development is that even though he seems more independent and always eager to move, he doesn’t like to get out of your sight and may even cry when you leave him alone in the room. Below are the changes to look forward to as the baby turns 10 months old.

  • Weight And Length 

Many first-time parents with 10 month olds may want to know, “What is the average weight of a 10 month old baby?”

On average, a 10 month old should weigh around 20.1 pounds for boys and 18.6 pounds for girls. The average length should be about 28.8 inches for boys and 28.2 inches for girls. The baby may have gained about half a pound or an entire pound and grown about half an inch from last month. 

But babies grow differently and sometimes you may wonder, “Why is my 10 months old not gaining weight?”

Well, there are three reasons why your 10 months old may not be gaining weight – not taking in sufficient calories, body not absorbing calories, or body using up too many calories.  It is best to talk to your pediatrician about it, but generally, most infants at this age add little to no weight because most of the calories they take in are used to fuel the active life they are living now. 

You do want to keep the doctor informed, however, just in case, but if the baby has added some weight, looks healthy and happy, and is achieving the 10 month old milestones as expected, then you shouldn’t worry. Your pediatrician will probably recommend increasing the number of times you feed the baby throughout the day, now that he plays more. 

  • The Senses


Baby can see colors well now. He loves to play with brightly-colored objects. He can also see objects with more clarity; he will see you coming from as far as across the room. Your little one can recognize familiar faces too (sometimes even people he has not seen for weeks). 


Your 10 month old listens to you when you speak and can now understand and attach meaning to words you say to him frequently. You may see him crawl to his shoes when you say “bye-bye” or stretch his arms toward you so you can go with him. 

He also understands the meaning of “No!” now and will often look at you (as if asking for permission) before he does something that will provoke a “No!” from you, or avoid it altogether. 


Baby at 10 months old is fascinated by everything he lays his hands on. He will touch objects of different shapes and textures just to know how they feel. 

Your little one’s pincer grasp has gotten pretty good now too. He will pick little objects from the floor and put them in his mouth just as he does finger foods at mealtime. Make sure you are examining your baby’s play mat and play yard frequently for sharp objects or choking hazards. 


Babies at 10 months old are mimics and will copy just about everything you say. Your little one will listen to the words you speak and watch your reactions to situations carefully. If you appear upset after a phone call or cry at an emotional gesture, for instance, your baby may also crumple up his face too or even cry. 

Your baby’s babbling has improved significantly from last month’s too. Those “mamas” and “dadas” are pretty clear now. He is even using them to describe you. How adorable!

If you are like most parents, at this point you may want to find out, “How many words should a 10 month old say?”

At 10 months old, most babies should be speaking their first word (“mama” or “dada”). But babies are different and grow differently; some will say up to three words (“mama”, “dada” and the name of his favorite sibling or toy).

So, parents who are wondering, “Can a baby talk at 10 months?” need to know that babies can talk at 10 months. However, most of the talking would be babbling, although you can still pick one or two meaningful words. 

  • Motor Skills 

Your little one is enjoying the freedom of moving around and discovering the world around him. Here are the physical skills to note in your 10 month baby development chart.

  • Crawling 
  • Cruising around while holding onto your hands or furniture. This is the perfect time to baby proof your furniture and living room, stairs, and fireplace if you haven’t already. 
  • Standing up without support
  • Taking steps or walking 
  • Pointing or crawling to the objects he wants
  • Clapping and waving “bye-bye”
  • Grabbing finger foods and putting them into his mouth 
  • Stacking bowls, cups, and play items
  • Bopping and bouncing to the music
  • Spotting objects quickly 

10 Month Old Food

Baby at 10 months is probably feeding himself (a bit). He may reach for a sippy cup or feeding bottle on his high chair tray or grab a pea from your plate at mealtime. Never leave baby feeding himself unattended though; you want to make sure he is not chocking. 

How Much Should A 10 Month Old Eat?

Exclusively breastfeeding 10 month olds should nurse about 4 or 5 times a day. Those who are bottle feeding should consume about 6 to 8 ounces of formula 4 to 5 times a day. If you are pumping breast milk, give baby about 25 ounces per day. 

But most babies at this age are already eating solids. If you are going to feed your little one baby food exclusively, make sure he is having at least three meals a day and a snack between meals (kind of like you). You may also want to supplement this with breast milk or formula because the baby still needs the nutrients he obtains from nursing. 

Is It Normal For A 10 Month Old To Lose Weight?

Yes, it is normal for a 10 month old to lose a little weight. This mostly happens because the baby at this age is more active and is moving more, which means, all the food he is consuming is being converted to energy to fuel his activities. Another reason why babies may lose weight at this age is an illness or not eating enough. If you are concerned about your baby’s weight, however, talk to your pediatrician. 

10 Month Old Sleep


Most 10 month olds will sleep about 11 hours at night and 3 to 4 hours at daytime (perhaps 1 ½ hours in the morning and the remainder in the afternoon). But some infants at this age may begin to drop their morning nap and taking one long nap in the afternoon. 

However, this transition will make your baby appear a little more cranky and tired than usual before he gets used to the new sleeping pattern. Sounds familiar? Try putting baby to bed for afternoon naps a little earlier if he just can’t stay without falling asleep. 

At this age, most babies will sleep through the night, although some may experience sleep interruptions thanks to teething. So, “How can I calm my 10 month old back to sleep,” you may ask? Try rocking, cuddling or just lying him back down and saying “it’s bedtime”. If this fails, try the food. All babies cry, period. But if you think yours is crying more than usual, make an appointment with your pediatrician. 

A Day In A 10 Month Old Life

A 10 month old is a busy little creature. His life is all about discovering how the world around him works. He will try opening doors just to see what is behind them, bang toys on the floor to hear how they sound, and test your boundaries (maybe your patience too!) 

Allow them to do their thing but don’t let them out of your sight. Importantly, offer a supportive environment for your 10 month baby development. Speaking of, some parents may ask, “How can I help my 10 month old development?” Here are some ideas:

  • Place safe objects in a low cupboard or drawer for your little one to explore and play with. Discovering stuff on his own will not only be thrilling for him but will also help lift his confidence. 
  • Teach baby simple gestures like nodding for “yes”, shaking his head for “no”, and waving for “bye-bye”.
  • Hide objects and help your baby look for them. This will help him practice and enhance object permanence.

When Should You Be Concerned?

While babies grow differently and may achieve their 10 month old milestones at a different pace, be sure to talk to the pediatrician if your little one displays the following symptoms:

  • Has not attempted crawling
  • Can’t rollover
  • Doesn’t respond to his name or any word from you
  • Isn’t happy when he sees relatives or people he knows well
  • Doesn’t make eye contact 
  • Isn’t able to sit without support
  • Doesn’t babble when you talk to him
  • Hasn’t added any weight in the last three months
  • Doesn’t feed properly
