What’s happening at this stage
Toddler sleep is a different sport: one midday nap, long 5–6 hour wake windows, and a small person with big opinions about all of it. The 18-month regression — boundary-testing, separation feelings, molars — is often the most stubborn one, precisely because your toddler can now actively protest.
The answers are consistency and warmth in equal measure: a rock-solid, predictable bedtime routine, calm boundaries that don’t wobble at 8 pm, and keeping the midday nap sacred (most children need it until around age 3). When the nap fails, rescue the day with an earlier bedtime.
Three things that help right now
- Routine is your superpower — same steps, same order, same words, every night.
- Offer controlled choices (which pyjamas, which book) to give autonomy without moving bedtime.
- Don’t drop the nap because of a protest phase; quiet time still counts on refusal days.
