One of the great things about being a triplet is that there is always a brother or sister willing to help you out. Recently, the triplets have been dealing with teething issues. Today we caught Betty sucking on Arthur's thumb, and later saw Coraline sucking on Betty's fingers. We are most concerned about Arthur's digits though, as Betty is the only one with actual teeth :)
And in fact, it was only a short time later, that Coraline started crying, and when we checked her hand, there was a tiny indentation on one finger from Betty's chomper. Perhaps this is the start of sibling fighting - "She bit me!" "He was licking me!" "Stop sucking on my hand!" - but for now, they are all still good friends.
