My kids giggled and giggled over the book about pressing the button! They also made me re-read the dot one about a billion times until I taught my little guy to look at the colors on each page so he could read it himself. The Bedtime Math book is great! It has varied ranges of math so both of my oldest guys can find something to solve. It’s fun to do one or two math problems each night and my husband loves doing it with them too. We’ve noticed an improvement in their math skills in only a couple of weeks.
