Any LO's going through this? She used to be a great sleeper. Would sleep 12 hrs straight through the night. But now is waking 2-4 times a night. I can't let her CIO bc she gets in a full blown panic attack like she cries hard!

Any advise on how to calm her? I have to hold her at the moment and sometimes even give her a bottle of milk to get her to sleep. Just don't want to cause bad sleep habits which I'm sure I am doing but im just tired. Lol

She has been sleeping in her own room/crib since 4 months old.
