The episode called "Little Ghost" needs some attention from parents. I'm glad I was watching with my 4-year-old son when that episode started so I could stop it on time. I watched with my wife later and we feel it's not appropriate for our son's age. We don't have a very good explanation about what a ghost is, which will make him even more confused. That doesn't do any good for kids this age whose imagination are so fertile, leading to bad dreams at night. That's definitely not funny for him nor for us.
My grandson loves "Dog." That's what he says when he wants a Kipper DVD. He has 3, so we haven't noticed repeat stories. Kipper is great when your child needs some quiet time - time to wind down, not up. There is no jumping and dancing, no excitement inducing songs. The narrator is very soft-spoken. We like Kipper and his friends.
