The reading level for this book says that it is for 3 year olds and up, but I think any child older than 3 will be bored with it. It's pretty much a simple counting book, with only the angry birds going for it. The counting changes in the book - sometimes you count only the same birds, sometimes you count different birds. So, while older children will be bored, younger ones may have trouble following it. My daughter who just turned 2 was a little confused. While she normally loves counting books, she quickly lost interest in this one.
