My lo's classmate bite her ear in childcare.The teachers told me that they did not stop them in time. Now her ear is swollen. Heartbreaking. :( What would you do when your lo being bitten?

For toddler, i believe they react in consistent manner. If it was my child who bite others, i would need to recap if my child always bites at home. if yes, it is a habit which i will put in effort to correct my child at home (hit on my child's palm and give time-out if happens right before me) and if no, it could be out of curiosity (i will let him try on himself... hee hee) or out of defense which i will show my child other methods he can use to defend himself.... all these, really takes time and effort to keep repeating and repeating until it has worked...
