Query: All time favoriet board book

I got this for my son when he was 4 months old. He loved the bright pictures and the story is really cute. It has become one of our favorite books. We have read it so many times that it is wearing out and I will have to replace it soon. I am surprised that it held up this long since he loves to chew on it as well and isn't very gentle with it.
