I am not very much a reviewer all i can say i got this book for my 2 year old son and i'm happy to say my son is done with diaper for good and now uses the potty.
i will recommend the book to anyone who is looking for a complete step by step guide for potty training and not those junks that is published on the internet.
and also the writer should work on the grammar, there were a few errors but it wasn't hard to know what she meant
