Have you seen the first Twirlywoos shows? These are short 15 minute episodes where a family of bird like characters discover something new in the human world. It teaches kids things like "round and round", "full" or "underneath". Each show is dedicated to a lesson/word. My DS is 3+ and loves it. It's short, simple and very clever. CBeebies - check it out. Also they have a game for laptop where your kids can squeeze fruit juice into a pot for the Twirlywoos. Cute! We love it. :)
