I have had my baby girl Kaya for about two weeks now and I cannot get her to stop biting me! We cant pick her up or pet her without her biting. She is only 12 weeks old and I know she is probably teething or playing, but how  do I make her stop? Her little teeth really hurt. Also, she is getting the hang of going outside to eliminate, but how do I teach her to go to the door to let me know? I will see her sniff and take her outside before there are any accidents.
