Super Heroes don't say "Mommy"

Norah has quit calling me "Mommy", and now refers to me as "Mom". Still a term of endearment to be sure, but I must admit I was a little bummed, as I was sure she'd be calling me "Mommy" for a few years yet. In any case, I just realized why this change has come about - Norah is a Super Hero. (a very nicely accessorized one at that) and everyone Super Heroes can't call their mothers by a name like "Mommy"
