I am really having a hard time with this. My DS is super sweet, but he has been biting at daycare for the last three months. I love to see him when I pick him up but don't love the bad reports for his providers. Being 30 weeks pregnant, I literally cried yesterday after getting to my car when they told me he'd had a tough day. We give time outs and tell him that it hurts people to bite them but I don't know how much an 18 month old understands. He doesn't have the words yet to convey to others he wants something or he is excited and then bites. It is really getting hard. Help! Advice? Suggestions?
