My son is two weeks old and has been crying in his sleep often and I don't know why...? Bad dreams?? But it only happens when he's not sleeping in my arms, on my chest, or right next to me pressed up against me.... but if he's in his bed or bouncy then out of no where he will just cry loudly and then stop and it's off and on until I pick him up and it stops... but he is completely asleep when he cries out like that...

Anyone know why or what it could be from and if I can help it?
