I like this book because it shows pictures of other toddlers sitting on the toilet. I use this to show my son that this is what he suppose to do. He is 18mths and understand concept well he just cant verbally communicate well so, pictures makes it easier. I read the book to him when we have story time and sometime at bedtime because I can never read the whole book in one sitting he just wants to do something with more action. I just started the whole potty thing this week and so far so good he acknowledges that he has urinate and have a bowel movement in his diaper now so he tries to tells us when he feels it. hopefully we will have great results by the end of this month.
