How do I get my daughter to stop throwing herself back when she gets fussy? She's done that & hit her head on the ground (carpet, but still she cried) & on my bfs head which she cried to because she hurt herself. She's been doing it in the tub too luckily it's in her little tub too cus it's easier for me to hold her but I'm scared she'll keep hurting herself. Is it a phase or how do I get her to stop
