Query: Useful Book

I bought this book to help my 15-month-old have fun on days it was too rainy or cold to go outside. He gets so bored and fussy when he can't go outside. It is most helpful for my Nanny, who doesn't have a car to take him to an indoor play space. There are a lot of useful suggestions and I like the way the book is organized
