Bobby, for your mom, check out Sephora (
www.sephora.com). They've got TONS of bath gift sets that are on sale right now. L'Occitane gift sets would go well with her French theme.
BDEyes, for your nieces, check out the Silver Jewelry Club website (from that other thread). I got my 12-y-o niece a necklace from there. The jewelry is so inexpensive, that if a child breaks it or loses it, you're not out much $$$.
