Baby nightmares

[GipsyDanger]

Probably a daft question but is it possible for babies at 2/3 months to have nightmares? Every now and then my ds will let out a cry in his sleep or he will do this and wake up crying, he makes this (adorable) sad face in his sleep as well. If it's not bad dreams any idea what it is

Don't know, but mine does this. I've always assumed it's maybe a windy twinge? Or perhaps dreaming, remembering an episode of crying earlier. I think our brains use dreaming to process memories and things, so would make sense? Maybe?

My 12 week old DD has done this a fair few times, let out a massive wail during an otherwise peaceful sleep without waking, it was quite alarming initially. I now just leave her unless she is genuinely upset & waking up. I probably leave her for no more than 30 seconds or so before going to her as I think that going to her too soon was waking her up when she wasn't really awake IYSWIM.
However last night she let out this enormous scream of fear, it frightened me so much that I screamed & woke OH too! DD was sound asleep still though, despite my scream & switching on all the lights looking for what had scared her.

Yes absolutely mine did this too. In his cot sometimes, but even while napping against me in the sling, he'd let out a wail but be fast asleep.
