So Jack told DH last night and Me today that he wanted ot watch the show him and I watched together and apparently whatever this show is the episode we watched had a  Dinosaur (he says its red), lady doctor, and lil boy and girl. I was trying to ask him more questions but all I got from him was "Let's not talk about this anymore mommy!!" so my question is does anyone have any idea what show this is!
