Toddler Sleep Regression Guide: Understanding the Science, Surviving the Nights, and Getting Back to Sleep

Your once-great sleeper is suddenly waking every hour. Naps have become a battle. Bedtime takes an hour of negotiation. If you're exhausted, confused, and wondering what happened to your child's sleep, you are not alone — and you haven't done anything wrong.

Toddler Sleep Regression Guide walks you through exactly what's happening in your child's rapidly developing brain during each major regression — from the well-known 4-month sleep reorganization through the 8-10 month, 12-18 month, 2-year, and 3-4 year windows — and why understanding the "why" makes the sleepless nights feel more manageable. You'll find practical, age-specific strategies, an honest and judgment-free look at different sleep training philosophies, guidance on nap transitions, nightmares and night terrors, and common triggers like teething, illness, new siblings, and potty training.

Just as important, this book doesn't forget about you: a dedicated chapter addresses your own wellbeing during the hardest stretches, because surviving a regression is as much about supporting exhausted parents as it is about the child. Grounded in real child development science and written with genuine compassion, this guide will help you understand what's normal, know when to call your pediatrician, and find your way back to easier nights — one honest, encouraging chapter at a time.
