I am also very disappointed with Treehouse and the new changes.
Monday was a very hard morning. My 2 1/2 yr old was expecting to have her usual 9 am backyardigans and suprise they are no longer then, it is replaced with My friend rabbit, which she did not like at all. Then she usually watches Diego as I make lunch, surprise that is no longer on then either, then to top off our day/night her usual shows have been pushed back and hour so at night so she didn't get to watch them. This happened about 6 months ago too, but it still had shows that she liked on. My daughter also loved Blue's Clues and Blue's room but is is rarely on when we have a moment to watch. Blue's, Dora, Diego all taught her so much, from sign language to Spanish and sharing, problem solving and using your imagination. They are all great shows that we miss alot.
For the new evening shows my daughter actually turned off the tv, because she does not like them at all. She turns off Fifi and the flower tots and In the night garden. I do not like the "telly tubby" like characters, they don't seem to talk proper, just make noises and don't really seem to teach the children anything.
I guess some people do not understand how routine oriented children can be. Mine has set tv times and expects certain shows as it is the routine.
For now we have started back with our collection of her favourite 20-30 min dvd shows and the Rogers on Demand kids shows.
