By bold colors and clean lines, the pictures are very interesting for babies, even if they can just look at it until (it's from 0+ months). If they are so far that you can grab and explore want (our daughter is there only at the beginning, 3 months), offers to book through the different materials and effects (crackling, rattling, squeaking) many interesting stimuli.
The hook is a maybe from time to time in the way, but because it offers the possibility of the book easy, for. Instance to the infant carrier to fix, I would not miss him. Maybe you could make the hook a button or Velcro detachable, but then you would back a verschluckbares part.
All in all, thoroughly recommended this book.
