I have a sil like yours.She never does for my daughter but always wants over the limit gifts for her 2.I have lowered the limit to 20 per kid because she always gives me 5-10 dollar higher gift.Meanwhile for my daughter I will tell her something for 20 and thats all she gets -nothing a little extra.For all my husbands cousins kids I spend 15.There are 7 of them and they always wind up getting my daughter more than what I tell them because they say I only have the 1 kid and they have 2 or 3.My sister and I usually do 50 a kid because we are closer.
