Milestones are helpful guides for what most children do around a certain age — not strict deadlines. Here's a parent-friendly map of speech and language development from birth to five, plus when it's worth checking in.
Every parent has wondered whether their child is "on track." Milestones can help answer that — as long as we remember what they actually are: a description of what most children do around a given age, with a healthy range on either side. Your child is an individual, not a checklist. Use this as a guide for what to expect and a prompt for when to ask questions.
Two quick notes before the lists. First, understanding (receptive language) usually comes before talking (expressive language) — kids comprehend more than they can say. Second, for bilingual children, look at what they can do across both languages combined; counting only one undercounts them.
Communication starts long before words. In the first year, most babies coo and then babble (those repeated "bababa" / "dadada" strings), respond to their name, turn toward sounds, and begin using gestures. Many say a first word or two around their first birthday. Early gestures — pointing, reaching, waving — are an important sign that communication is developing.
Expect a slowly growing handful of words, understanding of simple words and routines, and following one-step directions ("give me the ball"). Pointing to show you things and to ask for things is a meaningful milestone here.
This is often a vocabulary growth spurt. By around 24 months, many children use roughly 50 words or more and begin combining two words ("more milk," "daddy go"). They follow simple directions and point to familiar objects or pictures when named.
Sentences lengthen to two or three words and beyond, vocabulary expands quickly, and a child becomes easier to understand — often around half to most of their speech intelligible to unfamiliar listeners by age three. They start asking simple questions and following two-step directions. We go deeper on this age in what your 2-year-old should be saying.
Speech becomes clearer to people outside the family, sentences grow to four words and more, and children tell short stories, answer "who/what/where" questions, and use grammar like plurals and past tense (not always perfectly). Some sound errors are still completely normal at this age.
By five, most children speak in full, mostly grammatical sentences, are understood by almost everyone, follow multi-step directions, and can hold a back-and-forth conversation and retell events. A few later-developing sounds (like "r," "s," "th," "l") may still be in progress — that's typical.
If your child is a little behind on one item but doing well overall, that's often within the normal range. What's more telling is a pattern: several missed milestones, a gap that's widening, or the loss of a skill. Trust your observations — you know your child best.
If your child seems consistently behind these guides, or you simply have a nagging feeling, a speech and language evaluation is the clearest way to get answers. Reach out and we'll help you make sense of what you're seeing, in English or Spanish.
Often not — there's natural variation, and many children catch up. What's more important than any single late milestone is the overall pattern. If several are delayed or a gap is growing, it's worth checking in.
Look at what your child can do across both languages combined, not one alone. A bilingual child may know some words in each language, so counting only one language can make them look behind when they're not.
No. They describe what most children do around a given age, with a real range on either side. Use them as a guide and a prompt for questions, not a pass/fail test.
