Child Development Milestones
The first three years bring more visible change than any other stretch of childhood. Your baby goes from a newborn who can't hold their own head up to a 3-year-old who climbs, argues, and asks “why?” forty times a day. This guide to infant and toddler milestones gives you a rough map of that ground and simple ways to play along at each stage.
These are general patterns based on the kinds of skills the CDC tracks. Children vary widely, so think in ranges and watch for steady progress.
Smiles at you, follows faces with their eyes, holds their head up during tummy time, coos and begins to laugh.
Rolls both ways, sits with or without support, passes toys hand to hand, babbles strings like “bababa,” may show stranger anxiety.
Pulls to stand and may cruise along furniture, waves bye-bye, says “mama” or “dada” with meaning, looks for hidden objects.
Walks on their own, uses several words, points to show you things, tries to use a spoon, imitates chores.
Runs and kicks a ball, combines words into short phrases and then sentences, starts pretend play, wants to do things “by myself.”

Your pediatrician will check development at well-child visits, and the American Academy of Pediatrics recommends routine developmental screening in the early years. Between visits, mention it if you notice your baby isn't responding to sounds or your voice, doesn't make eye contact, isn't babbling or pointing by around their first birthday, or isn't walking by around 18 months.
The biggest red flag at any age is losing skills your child already had. Don't wait on that. Call the doctor. Every state also has a free early intervention program for children under 3; your pediatrician can refer you, or you can ask about it directly.
The free CDC Milestone Tracker app lets you check off skills as you see them and bring a summary to appointments. A notes app works too: jot the date of first words, first steps, and anything that worries you. Those notes make doctor visits more productive and give you a record you'll enjoy later.

FAQ
Around their first birthday, many babies pull to stand, cruise along furniture, wave, say a word or two like “mama” or “dada,” and look for toys you hide. Some walk; many don't yet. Ask your pediatrician if you have concerns.
Many babies say a first word around 12 months and have several words by 18 months, then start combining words around age 2. If your child isn't babbling, pointing, or using words when expected, talk to your pediatrician about a hearing check and evaluation.
Start with short sessions a few times a day while your baby is awake and supervised, and build up as they get stronger. Your pediatrician can give guidance for your baby. Lying on your chest counts.
It's a free or low-cost state program that evaluates and supports children under 3 who may have developmental delays. Your pediatrician can refer you, and parents can often request an evaluation directly.
