My daughter is a year and 5 months old and she has an extremely bad biting habit but she only bites out of anger , ive gotten criticized before posting things like this in other mom groups but I’m only asking for advice! She is a sweet baby but she’s got some real bad anger problems and this just started right after she turned a year old she will get mad and she will bite herself she will slam her head on walls/floor. No one has ever been mean to her. She is the only child and it’s just been me and her !

She bites so hard she breaks skin on me and on another baby in the recent past.
