The love for a grandfather for his unborn grandchild is touching and it is wonderful that Billy Crystal made it into a book for other families.
I bought this book for my father to read to my children. (Sadly, he didn't, but maybe he'll have another chance.) I cry almost every time I read it because the love of a grandfather for his daughter's child really comes through. It is simple enough for a child to read but ideally a parent or grandparent would read this to a small child.
