Child milestone checklists by age

Developmental milestones are the skills most children pick up around a certain age — the first words, first steps, waving bye-bye, stacking blocks, sharing a game. They’re a helpful map, not a stopwatch. Every child grows at their own pace, and reaching one a little late is usually nothing to worry about; what matters more is steady progress and the overall pattern across speech, movement, play and social skills.

Pick your child’s age below for a free, printable checklist of what’s typical at that stage, plus gentle guidance on the signs that are worth a closer look. If a few things aren’t there yet, it doesn’t mean something is wrong — it just tells you where to pay attention.
