I am trying to find a book that my 2 year old sister "read" to us because she had it memorized. I think it was a smaller sized "little golden book" it was something like "how big is baby" or "is my baby bigger than" it had a part about "is my baby bigger than a caterpillar munching on a blade of green grass"...she recently had her first child and I would love to find this book for her!! Thank you!!
