Your baby is now 16 months old and is walking, climbing, kicking, and playing most of the time. Some babies that hit 16 month old milestones a bit faster are even able to run at this age. If your little sidekick is a curious climber, you will need to childproof your entire home to make it safe enough. Babies will sometimes try to break out of the crib, so it is a smart thing to keep a carpet or rug beneath it. 

As your little one continues to make developmental bounds and leaps and continues to grow, he will certainly keep you on his toes. Keep reading to find out about 16 month old development milestones and whether your baby is reaching them in time!

What You Should Know

  • Your baby is growing in size and getting new skills every day. She will stay active during wake hours and you have to be there to supervise that she doesn’t get hurt. 
  • Walking is now a piece of cake for most toddlers. Be supportive and help your baby to start running, climbing, and dancing. 
  • Using at least 3 single words is considered normal for toddlers this age. However, if your baby is developing a bit faster she will be able to say up to 15 words without a problem. 
  • You might encounter some challenging behaviors as your little one is experimenting with things and trying to figure out what is happening around her. Be understanding and try to explain what’s acceptable and what’s not. 

Important 16 Month Old Milestones and Development 

These are the median measurements of a 16 month old according to the World Health Organization – 31.6 inches for boys, and 30.9 inches for girls. When it comes to weight, boys this age should have about 23.2 pounds and girls 21.6 pounds. 

16 Month Old Skills and Milestones

Your baby’s activity and social skills will tell you the best whether it is reaching 16 month old milestones in time. Here are some of the most important ones that you should pay attention to. 

  • Speech – Toddlers should usually be able to say at least 3 words when they have 16 months. Some of them that develop a bit faster and like to chat can know  15 words and more. 
  • Walking – At this age, most toddlers can walk pretty well without help. This will eventually lead to walking backward, dancing, running, and climbing. 
  • Potty training – There’s no need to force potty training yet. However, you should continue introducing your baby to the potty and what people use it for. You will probably notice that your baby is now starting to notice the potty chair or even asking to sit on it. 
  • Teething – Canines or cuspids eruption is a normal part of the 16 month old development. These are the third bottom teeth from the front and you might notice those white pearls during this month, so be prepared to soothe your baby if they’re painful. 
  • Behavior – You might encounter some boundary-pushing and challenging behaviors during this month. Find the best way to deal with separation anxiety, weird behavior, time-outs, and tantrums. 
  • Health – Food and drink preference of your baby can lead to numerous digestive problems. Besides, your baby will constantly be exposed to germs. Some healthy related issues you might deal with are diarrhea, constipation, and fever

Q: How many words should a 1.5 year old say?

A: Your baby should be able to understand all the simple words by now such as “bye”, “no”, or “bottle”. When it comes to vocabulary, your child should be able to use a couple of single words. Three to five words is decent, but some more advanced kids can say up to 10-15 words. 

Q: How can I encourage my 16 month old to talk?

A: The best thing to rely on is two-way communication. Ask your child something and wait for the response. Talk in your “adult voice” to help your baby better form the words and later phrases. Read books in a calming voice. Be relaxed, patient, and supportive.  Babbling is still talking and you should encourage your child to talk more clearly. 

16 Month Old Food 

As was the case with a couple of previous months, your baby should continue to have 3 meals and 2 snacks per day. Optimally, your baby should intake about 40 calories for every inch of her height. In other words, approximately about 1,000 calories during the day. 

Don’t be surprised if your toddler is eating normal one day and then not wanting to eat anything the other day. This is normal, and to a surprise, babies know very well whether they should be eating or not. 

Keep in mind that a serving size for a toddler is equal to ¼ of an adult portion. Encourage your child to use a spoon and fork when eating to make her more independent. Doctors warn that some sissy cups might delay a healthy 16 month old development of teeth. 

Q: How much milk should a 16 month old drink?

A: About 16-24 ounces of milk per day is the optimal amount. Your baby will get enough calcium, fat, and vitamin D through milk. But, you can always consult with your pediatrician about vitamin supplements. Don’t offer too much milk to your baby because it will be harder to gather nutrients from other foods if she gets full of milk.  

16 Month Old Sleep Schedule and Routine


If you want your baby to go through a healthy 16 month old development you need to make sure she is getting enough sleep every day. Most toddlers sleep between 11-14 hours per day. Usually, babies this age have 2 naps per day, but your schedule will might some rearranging since some kids start transitioning to just a single nap. 

Some moms might struggle to get their babies to sleep. Luckily, you can resolve this if you come up with a bedtime routine and stick to it every single day. Use noise machines if your child can’t fall asleep easily. 

Q: How many naps should a 16 month old take?

A: Some babies will have to nap for up to 3 hours during the day. Although toddlers usually nap 2 times a day, some of them will start to transition to just a single one. You need to find the best schedule for you and your little one and stick to it every day. Both 1 and 2 naps are fine.  

Q: Why is my 16 month old waking up at night?

A: The most common reasons why your baby is waking up at night are anxiety, fears, and stress. But, teething might also be the cause, in which case you will have to use a teething necklace to help your baby ease the pain. Read stories before bedtime and try not to expose your child to stressful situations. 

Q: How long can a 16 month old stay awake?

A: Your baby can stay awake for about 4-5 hours at this age. Still, you need to make sure that there are at least 2-3 hours of daytime sleep and 11-14 hours of sleep during the day in total. Sleep is very important to help your baby reach 16 month old milestones healthily.  

16 Month Old Activities 

At this age, there are numerous activities you can do with your toddler. Some of them are:

  • Pretend objects – Play pretend phones, toy booms, and kitchens and let your baby imitate your actions. 
  • Coloring – Always a great activity for the baby’s development and creativity. 
  • Blocks – About 50% of babies this age start playing with blocks, stacking them and making towers. 

When Should You be Worried 

As babies grow they will face some challenges when it comes to reaching certain milestones. This is perfectly normal and you shouldn’t be worried about that. Still, talk to your pediatrician if you notice these signs:

  • Too many tantrums
