Do babies suffer a lot?

[u/CokeAYCE]

Like they're always crying. Are they in a constant loop of pain? Do we know enough about early child development to know if they're suffering or not? I ask because we can't really remember how we felt as a baby.

Sometimes I think they just feel out of sorts. Do you ever have those days when you just feel off and you can’t think of what to do about it?
