18 Month Sleep Regression: Boundary Testing & How to Handle It

18 Month Sleep Regression: Boundary Testing & How to Handle It

Author: Sally Woods and Bec Maher November 10, 2025 Duration: 35:27

Your toddler's been a great sleeper for months. Then one night they start demanding more books, more cuddles, more everything. You're trapped in the room for two hours wondering what happened to your independent sleeper. This is the 18 month sleep regression, and it's less about sleep and more about boundaries.

Sally and Bec break down why this regression happens right when toddlers learn to use words to influence their world. They explain why giving in to one more book turns into 17 books by night three, how to hold clear limits without negotiations, and why it can still take two hours even when you're doing everything right. Plus the strategies that work throughout the day to fill their cup so you can hold firm at bedtime.

What You'll Learn:

• Why the 18 month regression is about boundary testing, not self-settling

• How language development triggers bedtime battles

• The exact bedtime routine strategy: verbal cues for last book, last cuddle, last kiss

• Why bore-to-reassure works better than negotiations

• Realistic timeline: 2-6 weeks regardless of your approach

• What happens when you try to max them out with long wake windows (spoiler: it backfires)

• Micro-moments of connection and choice throughout the day

• How to avoid creating new sleep associations while navigating the regression
