My fiance and I have a 10 month old son who at the beginning was great. He slept all night and never cried. However now he has changed a lot he is nearly walking and talking he is into everything and he has also developed a habit of biting and nipping when he is tired. Also when his mum is in the same room he is very clingy with her and won’t let her go. I am just looking for some advice to help us stop our son from nipping and biting.
