Do babies have nightmares??

[VeronikaMW]

My lo often cries in the middle of his sleep, I rush upstairs only to find that he is still asleep and stops crying a few moments later. He also often cries just before he wakes up but when I go in and he wakes up properly he seems fine. He does a lot of mantra crying to get himself to sleep (about 10 minutes) so is this just another form of it or can babies actualy have nightmares???

Anyone else experience this mid-sleep crying?

Josie does it when she is experiencing some wind or digestive discomfort. She cries and does a wiggle and then the bubble moves and she settles again.
