What's developmentally happening at 18 months
The 18-month sleep regression is driven by a stack of cognitive, emotional, and physical changes: big-boy/big-girl independence, molar teething, language bursts, and separation anxiety. Tantrums begin to appear around this age. The regression typically lasts 2-4 weeks.
This regression often shows up as bedtime refusal, crying at bedtime, and early morning wakings. Keep the routine predictable and short. Avoid starting new habits you wouldn't want long-term (like lying with them until they fall asleep every night) — these often become permanent.
Common sleep challenges at this age
- Bedtime refusal and cryingA consistent, brief goodbye. A lovey and night light can help.
- Climbing out of the cribIf climbing starts, the AAP recommends considering the transition to a toddler bed for safety.
- Nap strikeOccasional skipping is normal. Rare for a true nap drop at this age; hold the nap.
- Night terrors (not nightmares)Can start now. Stay nearby but don't wake. Usually resolves on its own.
