Alexandra Day’s playful book, Good Dog, Carl, features a dog who is left alone to babysit a baby. My daughter loves dogs. She loves dancing. She loves babies. There is nothing better than a book that features a dog dancing with a baby. Carl and baby get into lots of mischief, but Carl cleans up before the mother returns and all is well with the baby. Somehow, though, I still cannot quite get over the baby in a fish tank. I worry my daughter will try to emulate the baby in Good Dog, Carl not only by dancing, but also by taking a swim.
