"When you feel like you have to go, climb aboard the Potty Train. Chugga, chugga pooooo-pooooooooo!"
Ok, I know this sounds a little weird, but this really is a cute book for kids who are potty training. Nathan loves it even though he has pretty much mastered this "skill". It has cute illustrations and what kid doesn't like trains? If you have kids in this stage...have him/her climb aboard the toilet as you read this and hopefully the whistle will blow and your kid will be able to go chugga, chugga pooooo-pooooooo!
