This book has actually kept my toddlers attention and he wants to do these activities. He loves to go through the pages everyday. It has become apart of our routine and he gets so excited. I love that he can learn on his own if he ever wanted to, but it’s really great for teaching as you’re going along. It’s also great for coordination.Putting the Velcro together myself wasn’t too bad and actually quite satisfying to do, but it did take a while so be prepared to sit for a bit (I probably took longer than I would’ve because I was watching a movie while doing so).The only con I have is that I think my book was used as I was halfway putting the velcros on and I found a long mark from a marker. It seems they tried to clean it and couldn’t because I even tried and it barely budged. Not that big of a deal though because everything else was in good condition and it was too tedious to return, especially since my son loves it.Overall, I love this board book and I wish I discovered it sooner instead of trying to make my own as that was much more expensive and time consuming. This book is easily worth the measly $20.
