Thanks everyone. I'm not too worried about DCD asking for me to give his son another shot in the future... I'd just tell him no way. I think that my gut is telling me to just cut ties. I really like the little girl and it'll be a shame letting her go too, but I'd be stressing about DCD's reaction to every bump or scratch (she's just learning to walk so it's bound to happen!).

Appreciate your feedback. <3
