my daughter is 11 months and shes always slept in her own crib I've always laid her down given her a bottle and left the room for her to fall to sleep then I'll go back and check on her well recently she started this new thing where she cries if no one is in the room with her I'm not sure why shes doing this it doesnt matter where I am in the room I could be standing in the doorway as long as she sees someone she will go to sleep if not she'll cry for 20 minutes. I've tried a night light and lullabies does anyone have any advice or maybe have a clue as to why she started doing this?
