In the beginning of the month my 3 year old became a Sunbeam at church so I made him a little book bag for his own Book of Mormon.
Its been super good for his self confidence at church to have his own Book of Mormon especially in Primary. Plus we read out it at night during family scripture study.
I lined it with Cars Fabric. So technically its reversible, but I assumed he would keep the stripes on the outside. I was right, he gets so angry when his older siblings flip the bag inside out. I think its embarrassing for him.
