Real-life family notes

Screen time before bed (even background TV in the room) delays melatonin. Swap the last 45 minutes for books, bath, or quiet play.

What to do this week

Bedtime battles

Offer two acceptable choices (which book, which pyjamas) — not whether bed happens.

Nap guardrails

Cap nap by ~3:30–4:00 pm so night sleep pressure builds.

Language explosion

More words by day can mean more night calling. Brief, boring check-ins beat long negotiations.

FAQ

How long should an 18-month-old nap?

Often 1.5–2.5 hours once daily. If nights unravel, shorten the nap slightly or start bedtime earlier.
