My 1 year old son is biting me and my daughter. I don't think he's doing it to hurt us but he'll pull up on the couch to stand and cruise along it until he gets to me an bite my knees. Or today at the doctor's office he was getting sleepy while we were waiting for the nurse to come back in and he bit my cheek. He bit my daughter's leg today too he started crawling over her seemed happy and just bit her. She cried because it hurt. He left a red mark through jeans. My daughter is 12 she was so mad and really mad. Any advice is appreciated!
