He claims he can't. Whenever he is holding one at church, and someone approaches him and asks which twin he has, he shrugs his shoulders and says he doesn't know.
Whenever he addresses them, he just calls them "Baby", and they both respond.
Here's where I began to have my doubts, though. A few days ago, I told him that both the babies had had dirty diapers, and that I had just changed Twin B's diaper, but I'd really like it if he could change Twin A's diaper. He went to the living room, picked up Twin B, and proceeded to change his diaper. To me, that just seems a little too convenient.
What do YOU think?
Thanks for listening. :)
