Babies + Adopted Father

I guess nobody knows by now - but I've got new babies, specifically, this lot.

Henry is the big one, top left corner, two years. Accidental adoption, if you know what I mean. Next up, is Prometheus, hairless in the top middle. Farthest bottom right is Tiberius, black one next to him is Cornelius, hairless in the middle bottom is Barnabus, and far bottom left is Jerone, who is technically my brother's, but I care for him more. The babies are all around eight weeks.
