My husband has worked as a elementary school janitor for years. Many (if not most) of the teachers give or throw away the gifts they get at Christmas. Cookies are shared usually and other gifts, if you are lucky will be around until the end of the school year before they go in the trash. If you want to give the teacher what is on her classroom wish list. Maybe tissues for all the runny noses, hand sanitizer, anything that will make their job a little easier seems to be most appreciated.
