My two preschool kids have been gifted the Highlights magazine, which is really a great magazine, but unfortunately both my mother and my aunt have gifted it to them, so they received duplicates this month, and presumably will continue to for the next year.
Some of the materials are consumable activities, so it's fine for them to each have a copy, but I'm worried about my mom and aunt both feeling disappointed or hurt when they find out about each other's duplicate gifts.
What would be the appropriate way to let a gift giver know that their gift is definitely appreciated even if it is a duplicate?
