This is driving me nuts!! I can't think of a way to stop it. DS is almost two....he has gotten this habit of running up to me and biting me! If I strap him into the Ergo, he nips my shoulder or my back. If I change my clothes, he runs up and nips my bare legs. If I hold him with his head on my shoulder he starts biting my shoulder. It is SO PAINFUL! I don't know how the heck to fend him off. I think he's just being playful or sometimes even just joyful, but he has no concept of hurting me, and doesn't seem to care if I get upset. Any ideas?? Is this a phase anyone else has had?
