I got my son some pjs, some books, and some toys with a few treats in his stocking. He is only one this year, but I think when he is older we may take a trip as a family for his big gift.
I have seven younger siblings, most are still kids. I like to give them experience gifts. Example: Tickets to a movie or play, trip to the ice cream shop or a restaurant, sleep over at my house. They think this is awesome and it doesn't clutter their already crowded house.
