If she is homeless before moving in with your daughter I would hope she would be thankful that someone wanted to give her daughter something reguardless of if its a Christmas present or just a here is a present for your child gift. You are a thoughtful person for even being concerned about the mothers feelings. My ex husband was a Jehovah Witness and didnt turn away a gift my parents gave him. He was kinda selective when his religion mattered.
