Every child grows and develops within their own timeframe. As a parent, it can be difficult to remember not to compare your child’s progress to the children of your relatives or friends. One child may begin speaking early on, while another child may take more time. Rolling over, crawling, walking, and talking are all considered milestones. While the metric for measuring your child’s progress seems black and white, it is in no way a predictor of your child’s intelligence, talents, or future successes. 

Childhood milestones are different for each age range. These milestones develop over time, forming the foundation for growth and continued learning. In this guide, we explore the early childhood milestones, what they mean, and how to track them. 

Developmental Milestones From 2 Months to 2 Years

Your baby at 2 months
At two months, your baby is smiling at faces and taking in their new world. Babies at this age are social and love to interact with their parents. Their neck muscles are growing bigger and stronger, and they can hold their heads up for a longer time. They can identify and understand the tone, emotions, and comfort in your voice. 

What your baby is learning
While every baby is different, here are a few common milestones your baby may reach in this age group:

  • Lifts head when on stomach
  • Moves arms and kicks
  • Reacts to noises and understands voices
  • Cries and fusses
  • Starting to look closely at objects
  • Begins to smile at people

If you want to encourage your baby’s development during this time, experts recommend:

  • Singing
  • Talking and smiling at your baby throughout the day while bathing, dressing, feeding, or playing with your baby
  • Playing new sounds for your baby
  • Reading books out loud
  • Looking into a mirror with your baby

Your baby at 4 months
At 4 months, your baby is growing into even more of a social butterfly. Babies at this age love to make sounds like babbling, cooing, and mimicking other sounds they hear. They love to play and copy the movements of others. Also, your baby’s cries will begin to sound different as they learn to use their voice to communicate between tiredness, hunger, discomfort, and frustration.

What your baby is learning
Here are some milestones your baby may reach during this developmental period:

  • Makes sounds like “ooh” and “aah”
  • Briefly holds a small object
  • Pushes up on arms while on stomach

Things you can do to encourage your baby’s development include copying your baby’s sounds, singing songs while rocking your baby, making faces at your baby, reading with your baby, and helping your baby sit up with support. 

Your baby at 6 months
At 6 months, your baby is as social as ever. Your baby will use sounds to express emotion and will begin to recognize familiar faces. They mimic sounds they hear, like, “Ma, Da, Ba, Ah, Oh,” and even “No!” At six months, your baby will soon be on their way to crawling.

To encourage your baby’s development at this stage, take time to make music part of each day and continue to talk and sing with your baby. Get on the floor and play with your child, point and name pictures, praise your baby, and use big smiles and gestures.

Your baby at 9 months
By 9 months, your baby is getting mobile! Babies at this age are crawling and can begin to pull up to stand. At this age, it’s important to incorporate safety into your daily routines, as your baby’s mobility and curiosity grow. Your baby now responds to his or her name, loves to cuddle with family, and may show shyness or fear of strangers.

  • Starts to cling to adults they’re familiar with
  • Might be afraid of strangers

To encourage your baby’s development during this period, take time to read books together and name pictures, call your child by name, praise your baby for good behavior, and use finger foods to promote using hands to grab food. 

Your baby at 1 year
After baby’s first birthday, the rate at which they grow begins to decrease. By 1, your baby is officially a toddler. Toddlers are more active, curious, and expressive. Your toddler may begin to use words, stand on his or her own, and take a few steps.

Your toddler at 18 months
Your toddler is now walking and using basic words to interact with the world around them. At this age, children love to play and explore. They may play pretend and point at objects they want. They also begin to understand what things in the house are used for, such as kitchen utensils, or cleaning supplies like a mop or broom.
