I bought two of these Indestructibles for my 6 month old son and I am so glad that I did. The pages are thin like paper but constructed from tyvek meaning that he cannot tear them and they do not dissolve with slober (this is a biggie since my kiddo puts EVERYTHING in his mouth and the regular board books never look the same). They can be washed, chewed on, crumpled, and 'read' and they last through it all! Flutter! Fly! is just another fantastic story in the set. Though it does not contain words, it has pictures of all sorts of creatures that take to the sky, from a fly to an owl, and each creature has large and inviting eyes (b/c that's what babies focus on first, eyes). I have recommended this line of books to everyone I know, and anyone that shares with me that they have a baby in their family. I cannot wait for the new books to come out in this line as they are based on nursery rhymes and they are multicultural! I will definitely be buying more of these for my son and my neices!! I hope that your child enjoys them too! AND with overstock.com $2.95 shipping, you cannot go wrong!
