spark feeding

quick doodle of ember and ashbringer.
One of the many other theories which is not very developed actually is "breast feeding" within the transformers universe.
of course we don't know how they would even be born but whatever.
I imagined that on the first months breast feeding would be more like spark feeding, in other words the sparklings having acess to the mother's spark energy to feed them until they could drink regular low grade energon.
and since they're robots instead of boobs I made it more logical and just made it tubings.
