My son, the 17 month-old bookworm absolutely loves "Goodnight Gorilla," as well as "Freight Train." So simple and yet he remains fascinated. Sometimes I find him in his room flipping through "Goodnight Gorilla" just giggling to himself. And any of the "Baby Faces" books are great as well. We are finding that they are some of the first books our son can actually "read" himself (picture/word recognition). These are all good picks and great opportunities for cuddle time on a cold day.
