This learning toy is unpredictable. Sometimes when you press a button, another function will happen. The pages of the book have to be just right before it reads what is actually on the page. For example, on. the elephant page, it will still read "The ant is walking near the bee." My kiddo doesnt mind one bit, but it drives me crazy. I've tried changing the batteries, but it still happens No battery cover I can make custom bundles Thanks for looking!
