My 7 and 2 year olds love this show. I do not know why it is rated "iffy" for 2 year olds except that they may not understand the all of the content. That may make it a waste of time that could be better spent reading or doing something else, but it does not make it "iffy". It is never scary, violent, or inappropriate. It is s a show that these two age groups can enjoy together and you can feel good about having them watch. If you are going to allow your children to watch tv this is a great choice!
