Transitioning to own room

Erial

My husband is going to our of town so I have the chance to try and get our LO out of our room. She is 15 months and sleeps in her pack n play. She will go to bed on her own without us in there but she still wakes up anywhere between 3-9 times every night. She nurses at night only and I’m beginning to think it’s only for comfort. I make sure she’s full before bed.

I wanted some advice on how to help her sleep without me in the room. She wakes us crying for mama every time. I do a gentle cio.

Thank you !
