Anyone else dealing or dealt with 9 month sleep regression? Our lo used to sleep through the night for 12 hours and is now waking 2-3 times a night. She is pulling up on everything and pulls up to standing in her crib & screams. She is learning how to get back down but hasn't mastered it yet, which i think is part of the problem. Anyone have any suggestions on how to get through? How long did this phase last for you?
