This gets honest surprise. "No, I... I wasn't in the position to handle a child, and I barely knew anything about humans. I found a group who cared for foundlings and... well, offered to help pay them, and probably was a bit more threatening than I needed to be."

Because Bel really had trouble believing people took in orphans for the sake of wanting to care for children, even though he would have done it if he had any confidence in his own abilities. Hence the carrot and stick of 'I'm donating this money to you, but I will be keeping an eye on the kids, and you'll have more than a lack of funding to concern you if you don't treat them well'.
