How do most lose their tips?
Babies will bite each other for any number of reasons.
For example, babies tend to want to go over each other to get somewhere, and the baby underneath will sometimes bite the one climbing all over it. Or yes, one just has a bad attitude towards his siblings. Or they really do confuse each other's tails as food sometimes. They're babies, so they're not all that smart!
