Just that really. Have usually given a very small gift (a little bauble for the tree, or some homemade ginger biscuits) with a card made by DD to the teacher at Christmas break. DD's teacher this year is fantastic and an observant Muslim.
Would like to give her something, if only to mark the holidays and say thank you, have a nice break etc., but don't wish to offend. Any advice, particularly from Muslim MNers?
