Nub theory for twins. Any guesses?

Anyone wanna guess on my twins? I've got potty shots,but was wondering based on nub. TIA

Just a guess, but boys?!

It looks like they are both boys

Baby a I'm not sure. Think girl. Baby B boy

I'm guessing that baby a is a girl and b a boy x

Girl and boy?

I think B is a boy. But I can't tell on A. I don't see a clear nub.

Thanx for guessing ladies:)

I think both girls
