Do infants have bad dreams?

Dihanna

Not sure if this can ACTUALLY be answered. Do we know that they do? Havnt looked into it much yet but baby boy just woke up last night all of a sudden and crying. A little unusual. I know hes a baby and babies cry but it's a different cry. Like sort of half asleep and just the sudden loud cry! Then just falls back to sleep after I comfort and rock him a little.
