Thats disgusting...<br/><br/>But that is the point Fury. they need to learn how to feed, on humans, and safely. a lot of our characters were stored in pocket dimensions, lets say for simplicity they would have to start feeding at 13. before that it was like your original idea. (or breast-feeding! =D) They, being in pocket dimensions would have had to feed on the creatures in that dimension, and the few humans that our parents may have brought back. and we would've sucked them dry. I think as being what they are they would have no NEED to LEARN how to feed, but yes, do it safely and in a way to not attract attention.
