Why Newborns Have Jerky Movements During Sleep and Why It’s Normal

Did you know that Newborns often have jerky movements during sleep , and that is normal

Unlike other systems in the body, the nervous system matures gradually in the early years.

That’s why:

Newborns often have jerky, uncoordinated movements, because their nerves aren’t fully insulated yet.

Over time, as the protective covering (myelin) builds around nerves, signals travel faster and movements become smoother.

This natural process supports everything from crawling and walking to talking and problem-solving.

It’s a reminder that development doesn’t stop at birth, and the brain and nervous system are constantly growing, wiring, and adapting.

For parents, this means:

Give your child time and space to explore movement.

Don’t worry if early actions look “clumsy”, they often reflect normal maturation.

If you see persistent motor difficulties or delays, checking in with a pediatric neurologist can help rule out underlying issues.
