We already know he's fond of tattoos...
Changing my own opinion on this one - Lizzy says in chapter 21-2 that the tattoo on the little one's arm is fresh, so they can't be pre- Z-day test subjects because we're at least 3-4 months along the line by that time. A few episodes earlier Skittles says that they're really little, so I think I subscribe to the theory that they're children. Maybe very young when Z-day hit, or even still in utero? Do we know what happens to the baby if a pregnant woman is turned? Their growth would be totally extraordinary if that's the case, but then the Behemoths have gotten very big very quickly too, apparently with the help of the Raydon labs cocktail.

The suspense is starting to really get to me now :S
