12-month milestones (CDC): first words & walking

First words around 12 months

Around the first birthday, many babies are starting to use 'mama' and 'dada' with meaning, wave bye-bye, and understand simple words like 'no'; a first word or two beyond 'mama' and 'dada' often appears between about 12 and 15 months. Understanding words and using gestures count as communication too. Before clear words, you will usually hear babbling that copies the rhythm of speech and see communication through gestures.

Language at this age is built through everyday back-and-forth. Talking, naming objects, and responding to your baby's sounds and pointing all support words coming in. Some babies are quieter and focus more on movement first, then add words later.

• Calls a parent a special name like 'mama' or 'dada'
• Waves bye-bye or points to ask for something
• Understands simple words like 'no'
• Copies sounds and gestures during play

Standing, cruising, and early walking

Movement at 12 months ranges widely. Many babies pull to stand, cruise while holding furniture, and stand briefly on their own. Some take a few independent steps near the first birthday, while others are not walking yet, which is common.

Independent walking typically begins anywhere from about 9 to 18 months. A baby who is not walking at exactly 12 months but is pulling up, cruising, and moving with purpose is usually progressing normally. Give your baby safe floor time and stable surfaces to practice rather than relying on equipment that holds them upright.

Other things to notice at 12 months

Milestones cover more than words and steps. At this age you may also see your baby use a finger and thumb to pick up small items, hand you a book to read, and play simple back-and-forth games. Social and thinking skills matter as much as motor skills.

Use milestones as a checklist of what to watch for, not a test to pass. Note what your baby does and brings the list to checkups so your pediatrician can track progress over time.

• Picks up small foods with finger and thumb
• Puts an object in a container, like a block in a cup
• Looks for things you hide
• Plays games like pat-a-cake

When to talk with your pediatrician

Bring up any concern at the 12-month visit or sooner, since acting early helps. Mention it if your baby is not babbling, not using gestures like waving or pointing, not responding to their name, or not bearing weight on their legs when supported. Also raise it if your baby loses skills they used to have.

You do not need to wait for a milestone to be 'late' to ask. Trust what you see day to day, and let your pediatrician decide whether to watch, support, or refer for an evaluation.

Quick answers

My baby is 12 months and not walking yet. Should I worry?

Not walking at exactly 12 months is common, and many babies start anywhere from about 9 to 18 months. If your baby is pulling to stand, cruising along furniture, and bearing weight on their legs, that is usually a sign of normal progress. Mention it at the 12-month visit, and ask sooner if your baby cannot bear weight when supported.

How many words should a 1-year-old say?

Around the first birthday, many babies use 'mama' and 'dada' with meaning and understand simple words like 'no'; a first word or two beyond 'mama' and 'dada' often appears between about 12 and 15 months, and the exact count varies a lot. Understanding words, babbling, and using gestures like pointing and waving also count as communication. If your baby is not babbling or using any gestures, talk with your pediatrician.

Will baby walkers help my child walk sooner?

Mobile baby walkers do not help babies learn to walk, and the American Academy of Pediatrics recommends against using them because they are a leading cause of infant injuries, including falls down stairs. Babies learn to walk through supervised floor time, pulling up, and cruising on stable surfaces. If you have questions about walkers or your baby's leg movement, ask your pediatrician.
