My sweet daughter-in-law is expecting our 1st grandchild. Since we are a huge family of readers I asked my son & dil to give me names for some of their favorite books growing up. I bought a few of their favorites & since she loves hedgehogs I thought this would be a cute little book for bedtime. As our granddaughter starts to read by herself this will be a great starter book to have, too.
