From a first giggle to a first blowout — hey, it will happen, a lot — not all milestones will be cute, but they are important markers. During the first couple of months, it might seem all your baby does is eat, sleep, need their diapers changed, and cry because they want one of those other things, but then the 3-month-old milestones kick in and things get more amusing. See where your baby should be by month 3, and know what new, adorable adventures there are to look forward to.

Movement milestones

Your 3-month-old will love to move

  • Their legs and arms will kick and stretch when on their back or stomach
  • They will grab at toys dangled in front of them
  • They’ll discover their pudgy hands will chew on them
  • They’ll use those legs to push off surfaces

One of the best parts of this time is how interactive your baby becomes. Playtime is more or a two-way process, as baby has a wider range of facial expressions to clue you into how they feel. Your little one will follow objects better and be an active participant in playtime, rather than you just trying to entertain a ball of cuteness.

Tummy time

Most babies start tummy time sessions around a month old, but by 3 months old, they should be a pro at it. From being able to push their body up when on their stomach to perfecting the rollover, your baby should be able to support their head and upper body during tummy time.

Personality milestones

The noises kick in

  • Babble starts
  • Genuine smiles happen
  • They’ll look for the source of sounds
  • They start to love the sound of your voice and will smile when they hear it
  • They will start mimicking noises
  • They begin to make eye contact

The introduction of adorable noises and smiles will melt your heart. Your 3-month-old will start to find their voice while having sounds they enjoy light up their face. From those first smiles to magical baby babble, the precious noises will fill your day.

Eating and sleeping milestones

How often baby eats

  • A breastfed baby will nurse around every 2 to 4 hours
  • Formula-fed babies will eat around 6 to 8 times a day

Your babe should be able to go a few hours between feedings now.

Sleeping at night gets better

  • They’ll sleep around 14 to 16 hours a day
  • They will take up to three naps a day, just over an hour each

The newborn zombie walk new parents do will start to wear off a little. A 3-month-old will sleep most of the day, with a good portion of it overnight, which is good news for parents. There should also be a longer stretch between those nightly feedings.

Sticking to a sleep schedule

By 3 months of age, you should have a sleep schedule established. It should be the same time every night for bed, the same time for naps, and then everyone should get more sleep than they’ve had since baby came home.

Other milestones at 3 months old

Your baby has favorites

Around this time, you might notice your baby has favorite things. This could be a person, a toy, a room, or a noise, like music. Not only favorites, but by 3 months, your child will be able to recognize people or places they see often.

Your baby loves hugs

While skin-to-skin time is still something baby and parent should be doing, your little one will grow fond of hugs. While that is good news for everyone who loves a good baby squeeze, it’s also beneficial for the baby, as it helps with cognitive development.

Milestones a 3-month-old won’t hit yet

  • Not quite ready for solid food
  • No water or other liquids besides breastmilk or formula
  • Won’t sit up alone

Parents are always excited to watch their baby try food for the first time, but it’s a tad too early for solids. The recommended age is 4 to 6 months old, so don’t start making baby purees just yet. It’s also too soon to introduce any other liquid to your baby’s diet, and that includes water

Your 3-month-old can’t sit up by themselves but could fake it if propped up with support. Playtime will still have to happen on the floor or on your lap.

Not all babies hit every milestone by 3 months

3-month-old milestones misses

  • No smiles for people 
  • Doesn’t follow objects with eyes
  • No eye contact with people
  • Isn’t holding onto toys/other objects
  • Hasn’t discovered their hands
  • No reaction to loud noises
  • Legs don’t push off of surfaces

Every child is different, and not every baby will hit every milestone exactly at each month. If your bundle isn’t hitting all 3-month-old milestones, don’t panic. Keep your eye on their overall development, and if you notice these aren’t being met or have concerns about your child’s growth, let your pediatrician know. 

As your child gets more vocal and active, opportunities to bond by more than just staring at each other are available. Enjoy this little sweet spot before you have a crawler, and everything becomes a game to catch baby.

As your little one approaches the four-month mark, you may soon be getting what you desperately crave, a good night's sleep. A baby's sleep schedule begins to change around the four-month mark. As babies reach this stage, the 4-month-old sleep schedule begins to change as little ones start to enjoy more awake time.

You have probably noticed your baby staying up for longer periods of time during the day and sleeping for lengthy stretches during the night. Both of you are probably having fun during those awake hours. Parents are definitely savoring the extra hours of sleep during the overnight hours. Even though babies love being awake more during the day, solid nighttime sleep and naps are still important. So, what exactly does a 4-month-old sleep schedule look like, and how much sleep does a baby need at this stage?

Father burping his baby

As an adult, there is nothing that brings you to your knees like getting the hiccups. Imagine how it must feel to be a new baby and get the hiccups. If you have noticed your bundle making those telltale noises, this is how to get rid of baby hiccups and prevent another attack from coming on.
When a baby hiccups

Baby's first hiccups
You might not remember the first time you had the hiccups, and neither will your baby. It might sound a little like a sci-fi movie, but your baby could have had hiccups while still in your stomach. There is no way to know just by feeling your stomach, but those little kicks could have been baby hiccups. 
Baby's next hiccups
A baby can have hiccups the second they are born. As humans with organs that have natural reflexes, we all could get the hiccups at any age. But because a baby doesn't quite know how things work yet, infants up to 12 months old tend to "catch" the hiccups a lot more than at any other time in one's life.
