Fussy 1 year old
Not quite sure what it can be. Possibly teething. My baby girl hates sleeping in her crib now. I used to be able to put her down & leave the room and she would fall asleep. Not anymore. If I leave the room she just wails. Once I finally get her to bed she wakes up again during the night & screams again. She won't go back to bed unless I'm holding her. Thus hasn't happened since she was 9 months.
