My 9 month old baby goes through phases of crying in her sleep. It's for no more than a couple of seconds and her eyes stay closed. Last night for example, she did this at around 10pm, 12.30am, 1.30am, 2.30am, 3.30am and 5am. Is this something anyone else has experienced? Do you think it's teething or nightmares? I don't think there's much I can do about it is there? I feel bad for her and I'm also fairly tired from the wake ups because although she doesn't wake up, I do and it then takes me a while to fall asleep again.
