Which is your child?

You are at your son's football practice and because you can't leave practice, you are chasing your baby daughter around, trying to keep her out of trouble. At the end of practice you notice a group of parents signing with each other. This is your opportunity to introduce yourself.

Do you grab your baby, walk up to the group and introduce yourself saying your son is #12 and asking who their children are?
Do you introduce yourself as a working interpreter?
Do you walk the other direction because you don't want to get involved?
Do you feel awkward because you don't want to be the person who is like, "hi! I can sign too!"
