Buy the book! Purchased this a second time as our toddler loves it so much and our first copy was very loved. The board book pages are thick and sturdy holding up well to impulsive throwing. Flaps are easy for little fingers to open and this is hands down our 18mo olds favorite book and she runs over with it daily to "read". Lots of fun things to point to to practice speech as well.
