I did want to mention an alternative to tangible gifts, though, since a few friends have been asking recently what I tell my family members when they ask for gift ideas for the kids. Oftentimes, for birthdays and Christmas, I have suggested a membership to a museum or some contribution towards a class that our children would enjoy. For example, we have received memberships to the children's museum and zoo in the past, as well as Gymboree classes, swimming lessons, and an after-school science class. These have all been very much enjoyed by our kids, and I make sure to remind them several times of who has given this to them as a gift. I also send a thank you note with a picture of my child enjoying the activity, so that it's more tangible to the gift giver.
So, while there is a certain amount of joy and delight that comes from unwrapping gifts on Christmas day, this can be an alternative for the relative that is out of gift ideas!
God bless all of you in your Advent journeys!
