Question

Babies wake up almost every two hours or so, then why say, “sleep like a baby”?

Answer 1

because they are fast asleep right when they go to bed so not when they are waking up and stuff but right when they fall asleep

Answer 2

Because the baby looks like an angel when actually asleep...so technically sleep like an angel

Answer 3

Thats because babies normally slep very comfortably and peacefully. They usually dont stir or move much at night. They sleep hard and dont tend to hear many noises. I wish I sleep like a baby every night ...... = )

Answer 4

cuz when they are asleep, they sleep deeply.

Answer 5

Because when a baby is sleeping they sleep peacefully with no worries about what's gonna happen tomorrow. They also have no trouble falling asleep because they're just so careless. Babies also don't stress or overwork themselves so they sleep with no worries.
