So this was my second diaper cake. They are so easy. Here is how to make a diaper cake. Baby shower Sport themed 49ners football boys I like to decorate them with: a hooded bath towel,bottles, pacifiers, bibs. On my last one the top was a stuffed animal. I like to ask the host of the shower the theme so I can try to match the cake to it. :) Good luck and have fun!
