Evening fellow bbers!

I was just wondering if babies have nightmares cos 2 evenings in a row lachlan has woken up all of a sudden CRYING. he NEVER wakes up crying - not ever. its like he's upset about something and i put his dummy in rock him, pick him up and seems ok. check his lil bod etc to make sure nothing wrong there.

the odd thing i was thinking was he's woken up around 6pm - he was born at 6.18pm. he's not dreaming bout his birth is he - i mean babies have no concept of time really huh?

probs a stupid q but just wondered anyway.....anyone?
