Take them, thank her and then re-gift them. Is there some sort of playgroup/kindy/whatever fundraising raffle you could donate them to? Drop them at the food bank where a child might like a gift of a chocolate egg.
Yes as above. Some people you will never get to really take in the message of no-gifts, or if they take in at all do a big guilt trip about ruining the enjoyment of the gift giver. (My take is what about my enjoyment of having a flat that isn't constantly over-spilling with stuff, and yes I can re-gift, donate etc but really we prefer the gift of space) After nearly five years have finally got through to the IL's that if they must buy gifts for the kids (which are flown over from the UK - postage often costing more than the items - never mind the environmental impact of it all having been flown from China to the UK and then over here) make them clothes because I don't buy any so they will get used. (But still sometimes they still send a chocolate advent calendar - you can imagine the state that is in having flown from UK and maybe sat in the mail box or on our doorstep all day in December).
