I ordered the princess ones for DD's and the regular blue Mickey and characters book for DS. They arrived yesterday and I was surprised how small the blue one was (4x6 pages whereas the princess book is 5x7). Are the pages big enough or should I go for a larger size? Is there a different one that I can get that is boy friendly and not too expensive. I'd love to make my own but there is no way that will happen! Thoughts?
