Why do babies have to take a nap?
Babies need to sleep because sleep renews energy and their
bodies are using up so much energy growing that they could not go a
full day without taking naps. So while they are sleeping, their
bodies are resting and renewing themselves so they can continue on
learning all they are learning and their cells can reproduce and
make more bone, skin, hair and anything else that keeps getting
bigger as they grow.
