Why do sleep problems happen from 0-2 years?
Sleep in the first two years changes fast. What looks like "random bad sleep" is usually a pattern linked to timing, development, and routine.
This baby sleep guide 0-2 years gives you a practical map and links to detailed step-by-step guides.
Wake windows by age
Wake windows are one of the strongest levers for better naps and nights.

Night waking patterns
Night waking is common, but the reason usually differs by age and routine.

Frequently asked questions
Is this baby sleep guide 0-2 years a strict schedule?
No. Think of it as a decision framework. You adapt timing to your child's cues and real daily pattern.
What should I change first if sleep is hard right now?
Start with one variable: wake time, bedtime timing, or nap rhythm. Track for 3-5 days before changing the next thing.
