Editor: Kirandeep Kaur on Jun 20,2025

 

Learning about tracing a baby's milestones: 0–12 months is the most significant path that a new parent can embark on. From the initial smile to the initial steps, every second counts as it is a milestone that gives you a clue to your baby's growth. Whether you wonder when the baby sits, rolls , crawls or needs a motor milestones chart, tracing progress ensures that the baby is growing at the expected rate.

In this guide, we'll discuss infant development milestones such as movement, language, and social signals. We'll also give advice on tracking baby development apps and what to do if you have concerns about milestone delay. 

Why Tracking Infant Development Milestones is Important

The first year is a time of amazing and rapid growth for your baby. During this time, the brain, muscles, and social skills begin to appear and develop at remarkable speeds. Watching for infant developmental milestones helps you and the pediatrician recognize development status, and it can help identify any developmental delays early on. By being aware of early cues, parents can foster learning and engaging play routines and recognize developmental challenges sooner. Just remember, every child develops at their own pace. These milestones are thoughtful averages—not hard and fast deadlines.

Monthly Breakdown of Baby Milestones (0–12 Months)

Let's look at the major infant development milestones month by month. These categories are sorted by motor skills, speech, and social development.

Month 0–1: Reflexes and Basic Responses

  • Motor Milestones: Rooting reflex, grasp of fingers, turning the head in response to sounds.
  • Speech: Crying for needs (hunger, discomfort).
  • Social: Eye contact, responding to known voices.

At this stage, monitoring baby development apps will be useful for recording feeding, sleeping, and responses.

Month 2–3: Early Social and Physical Skills

  • Motor Skills: Holding head up for brief periods.
  • Speech: Start of cooing and gurgling.
  • Social: Smiling at faces, tracking objects with eyes.

Check your motor milestones chart—this is when babies start strengthening neck and head control.

Month 4–5: Babbling and Rolling

  • Motor: Rolling from back to tummy.
  • Speech: Laughing out loud, playing with vowel sounds.
  • Social: Laughing, getting to know parents.

If you are asking when does baby sit roll crawl, this is when rolling often starts. Get tummy time

for supporting stronger muscles.

Month 6–7: Sitting and Reaching

  • Motor: Sitting with support, reaching and grabbing.
  • Speech: More sounds, changing tones.
  • Social: Responds to mirror reflections, responds to strangers.

This is an important milestone on your motor milestones chart. Babies will begin to sit for a moment or two without support.

Month 8–9: Crawling and Imitation of Sounds

  • Motor: Crawling, pulling yourself up to stand.
  • Speech: Imitation of sounds "ma" and “da.”
  • Social: Attachment to familiar individuals, stranger anxiety might set in.

Still not sure when the baby sits and rolls crawls? Crawling usually begins between 7–10 months but is highly variable.

Month 10–11: Cruising and Word Construction

  • Motor: "Cruising" while carrying furniture.
  • Speech: First distinguishable words such as "mama" and "dada."
  • Social: Playing games such as peekaboo, waving bye-bye.

Continue using tracking baby development apps to record speech and movement milestones.

Month 12: Standing and First Steps

  • Motor: Standing independently, making first steps.
  • Speech: Comprehends simple commands, 1–3 words.
  • Social: Displays feelings, demonstrates preferences.

You’ve reached one of the biggest infant development milestones—walking. Celebrate it, but also remember that many children walk between 12 and 15 months.

Understanding Motor Milestones What’s Normal?

A motor milestones chart helps track physical activities like grasping, crawling, and walking. Below is a basic guide:

From 1 to 3 months of age, babies start to develop some neck strength and can lift their heads for brief periods during tummy time. By 4 to 6 months of age, most babies can roll over and can often sit with some support. By 6 to 9 months, most babies will sit without support and start to crawl and explore their environment. By 9 to 12 months, many babies will stand with support, cruise along furniture, and may take their first independent steps.

If you're comparing it to others, don't worry—babies grow at their own pace. The trick is monitoring consistency over the long haul.

Speech Milestones: Cooing to First Words

Speech development is another significant field of infant development milestones. Below is what one can expect in speech development milestone first year:

  • 0-3 months: Crying to communicate needs, starting to coo,

  • 7–9 Months: Looks when called, uses gestures.
  • 10–12 Months: Saying first words, comprehending simple sentences.

Speak to your infant frequently—describe routine activities, sing, and repeat their sounds. Earliest exposure enhances vocabulary and conversation.

When to Be Alarmed by Milestone Delays

Though milestones differ, there may be some signs indicative of milestone delay issues:

  • No head control by 3 months
  • Not sitting at 8 months
  • No babbling at 6–7 months
  • No crawling or standing at 12 months

If you're worried, speak to your pediatrician. Getting a head start really can make a difference. Most delays can be addressed with therapy, changes in lifestyle, and regular monitoring.
