“Im just wondering does anyone have any ideas on what to do/say to a 10 month old when they are hitting or biting people? My 10 month old bit her 3yr old cousin on purpose yesterday. Before this he kneed her in the head, she bit him when he was trying to say sorry. It made him cry and I didnt really know what to do about it. My fiance and I have decided not to use smacking as a punishment and when she is older we will have a naughty mat, but I think she is too young for that at the moment. So im just after some tips on how to chastise a 10 month old. Thankyou.” Any tips for a 10 month old biting and hitting?
