I bought a regular Bible for my godson and a children’s Bible for my goddaughter. (Same family.) I also regularly buy them Christmas gifts to enrich their faith - children’s books about the faith (I bought one called “The Weight of a Mass”, based on a true story about how not a single item in a shop could equal the weight of a piece of paper with the words “One Mass” written on it - the Mass always weighed MORE; the kids LOVED the book), children’s books about the saints, etc.
