I bought this book in July 2009 for my daughter who is now 3 months old. It's definately one of her favorites - especially the first page which is crinkley, so she loves to grab it.
I think the bugs have changed over the years though, because our book doesn't have a spider or fly or some of the other bugs mentioned in other reviews. It has a bee with a fuzzy body, a ladybug with glossy spots, a snail with a kinda shiny shell, beetle with shiny wings you can grab, dragonfly with netted wings you can grab, worm made of corduroy-like material, and a butterfly with a shiny fabric wing you can grab.
The book's tag recommends you surface wash only; however if I throw everything in the washing machine (if it can't withstand a thorough cleaning, I don't want it). The colours faded noticably after 1 wash and the crinkley material in the first page ended up in one corner.
Still, this is definately one of my 3-month old's favourite books.
