Why do babies cry when they wake up?

AaliyahWhy my baby wakes up and crying?
Danielle: Crying is the way babies communicate discomfort. It's normal for babies to wake up hungry and/or with a dirty diaper. They don't like either state of affairs. If you address those two issues, and the baby is still distressed, there may be something else going on but 85% of baby complaints involve an empty tummy or a dirty butt.
