My 3 and a half year old really likes his Raffi Down By The Bay and Toddlers Sing. We have a Weesing but I find it to be annoying. My personal favorite is The White Album which is done with a jazz type piano and soft vocals, it's really nice and easy to listen too, great for winding down. I am looking for recommendations outside of the mainstream Barney and Elmo stuff. We also liked Kindermusik cds but have only the ones for younger kids. My ds doesn't like any of the rock albums they try to gear to kids either, he says, "that's Daddy music, I want kids music."
