This idea came to me as I was listening to Swedish war metal on my way home from work. Is it hemalurgically possible to steal abilities from someone who had not yet had the chance to use/manifest them... such as a baby? In a similar vein, could you spike a pregnant woman through her stomach and (with enough precision) transfer her abilities directly to her baby? What would spiking a person that young even do to them? If both the woman and the baby had abilities and you spiked the woman, whose abilities would you get? How far from the baby do you have to spike to make sure you get the woman’s... you know what, I didn’t mean to get this close to political debate. Sorry.
