Your baby was sleeping fine. Now they're waking every 45 minutes. Here's the science behind the 4-month sleep regression — and what actually helps.

Tummy-to-back rolling peaks at 3–4 months. Back-to-tummy follows at 4–6 months. Here's the complete timeline, what tummy time has to do with it, and the swaddle safety rule.

Cooing at 2 months. First words at 12. Sentences by 30. Here's the complete language development timeline — with the red flags pediatricians actually watch for at each stage.

Most kids are ready between 27 and 32 months — not at 2. Here are the readiness signs that actually predict success, and the ones that don't mean anything.

Your pediatrician runs this screening at every 18-month visit. Here's what it measures, what a positive result actually means, and exactly what to do next.

Fewer than 50 words by 24 months, or no two-word combinations — those are the two clinical flags. Here's what counts as a word, what to do, and what "late talker" actually means.

Ten words by 18 months is the clinical benchmark. Here's what counts, what to do if your toddler isn't there yet, and why early intervention at this stage is highly effective.

The crawling window closes at 10 months — not 12. Skip crawlers are real. Here's what the clinical flag actually is and when to mention it to your pediatrician.

Eye contact is a social milestone, not just a reflex. The social smile and eye contact window closes at 3 months — here's what to watch for and when to act.

Consistent name response is expected by 7 months — not 9 or 12. Here's the window, the test, and what absent name response means for hearing and social development.

Understanding language but not producing it is called expressive language delay — and it still warrants evaluation at 24 months. Here's the distinction and what to do.

The walking window closes at 15 months — that's the clinical flag. Cruising and pulling to stand are precursors. Here's the full progression and what to raise at the well-child visit.

Declarative pointing by 12 months is the single strongest behavioral predictor of autism in the first year. Here's the imperative vs. declarative distinction and what the flag means.

There are two rolling milestones: tummy-to-back closes at 5 months, back-to-tummy closes at 6 months. At 4 months, you're likely still inside the window — here's what applies.

The social smile window peaks at 6 weeks and closes at 3 months. At 3 months, absent social smiling is a clinical flag — here's what a social smile actually is and what to do.

Sitting with support is expected by 6 months. Sitting independently isn't expected until 8 months. Which milestone applies to your baby right now changes everything.

Babbling should be established by 6 months. At 9 months without consonant sounds, you're 3 months past the flag — here's what to do and what to rule out first.

The 8-month regression isn't structural like the 4-month one. It's separation anxiety, object permanence, and motor leaps colliding at once. Here's what drives it and what helps.

Language explosion, toddler autonomy, peak separation anxiety, and molars — all at once. Here's why the 18-month regression hits harder and what actually gets you through it.

Pointing is expected by 12 months. An 18-month-old not pointing is 6 months past the clinical flag and missing a primary M-CHAT-R/F item. Here's what to do now.

Separation anxiety is now fully wired. Object permanence is locked in. The motor leap is peaking. When those three things land at the same time, sleep falls apart. Here's what's actually happening and what helps.

Your toddler now has enough language to argue, enough autonomy to resist, and enough cognitive development to turn bedtime into a negotiation. Four things are happening at once. Here's what they are and what actually helps.

Strangers should understand 75% of a 3-year-old's speech. Some sounds (r, l, th) aren't expected until age 5–7. Here's the distinction that matters — and when to act.

The crawling clinical flag is 10 months, not 12. At 12 months without crawling, the real question is: are they pulling to stand? Here's what matters now and when to act.

By 8 months, babies need solids for iron. The texture window closes at 9 months, creating risk for picky eating. Here's what to prioritize if your baby isn't eating solids.
