As a mother of a toddler who loves this show, I have to write a good review for it. The shows (and the songs) have helped her learn to use the potty and to share. Yes, that's right, my daughter was potty trained by 2 and I credit this show, in part. There are lots of great lesson that have helped her navigate life and play with friends. And as she grows older, we revisit shows that have lessons relevant to her life. I don't mind watching the shows repeatedly too. The songs do stick in your head, but now we make up our own songs for all sorts of things.
I grew up watching Mr. Roger's Neighborhood, but my memory of it is fuzzy. So, I am not upset about the changes.
