Hi Welcome to YT
To you and your babies!! Its unusual for a littleone to get so aggresive!! although play fighting can get abit out of control!! maybe he is trying to show her he wants to be boss!! but I cant see him getting that off a girl!! Try telling him off! If that dont work pherhaps you should think of taking him to obediance class!! Good luck Love Wendyx Fifi
And Lulu
