The books are very easy to use. You simply open the door on the right side of it and switch the switch to record. You record each page one by one. When you are done recording, switch the switch back and your child can't accidentally record over anything. You do have to make sure when reading the book that it lay flat or almost flat. If it isn't, it will not play that page. My son, who is 3, usually does not have trouble getting every page to play without a problem. Sometimes he tries to listen to it laying down and then it will skip a page or something. He has to read his book almost every night before bed. His dad & I recorded our voices on every other page so he can hear both of us whenever he wants. He absolutely loves it.
Be sure to try it for yourself and give this joy to your little one too!
