I need some help.
My nephew is 14 months old and he is constantly biting my 21 month DS. My sister looks after DS 2 days a week and I look after my nephew 1 day a week.
Everytime DS goes past him or even in the same room sometimes, my nephew attacks him!
DS is starting to bite back now which I didn't want as he has never been a biter!
My sister is not being consistent with her discipline for her son and I don't know what to do!
Has anyone else got any advice to stop this ASAP?!
