    Your Baby’s Brain at Night: What’s Really Happening During Sleep

    Sleep Is Brainwork

    Your baby’s brain is busy at night.

    During sleep, they:

    • Process new skills
    • Store memories
    • Regulate emotions
    • Build physical growth hormones

    REM = Brain Development

    Babies spend 50%+ of their sleep in REM—light, twitchy, active sleep that looks anything but peaceful.

    That’s not poor sleep. It’s productive sleep.

    Night Wakings Are Part of It

    As your baby learns to crawl, babble, or sit—they may wake more.

    That’s not regression. That’s development.

    Final Thought

    Sleep isn’t just rest. It’s rapid growth. Support your baby through it with calm routines and predictable care.
