I loved this book when I was little, so I took a shot and bought for my oldest when she was born. Turns out, she loves it! I tried it on my youngest, who is now 10 months old, and she loves it, too! They both love how animated I make Grover during the story. My oldest, who is 4, practically has it memorized and loves all the things Grover tries to do to keep us from turning the pages. It's a great, fun read that we've been enjoying for years!
