my daughter (only 10 months) has this as well. just a week or so ago i was talking to my friend (who has 2 kids with it), and happen to say that my daughters space was due to the binky, but she corrected me and told me it was because of this fraenum. her dentist told her that most kids end up falling at some point and hitting their mouth, at which point it tears on its own, but does bleed a lot. wanted to assure her that it was ok -- not to be scared. but did say that if that doesn't happen, they'd need it clipped before braces when they're older. with all the falls these little ones take i'm sure dentist is right and it corrects itself that way at some point.
