Underwear Do's and Don'ts wasn't geared toward my 8 year old niece or to me, but it was highly entertaining for my 4 year old nephew who is an underwear newbie. I'm sure that in about 10 years he'll love that I just typed that, but I digress...
The colors are bright, the pictures and text are silly, so this is just the kind of book that is likely to make a pre-schooler guffaw. My nephew did enjoy it, but I think that the book lacks memorability. I'm pretty sure that my nephew had already forgotten about this story almost as soon as we closed the book.
