Chuggington is way better! Much more colourful and fun and has so much more energy in it. ds is only little so doesn't watch that much tv but I think he's only even seen Thomas once or twice. my dh likes Chuggington much better too so there will be arguments in our house. I also got ds a Chuggington doona cover when he was 8 months old We co sleep but we bought a good double bed for his room so the doona cover is on that. Did your ds play with it ok when he was 2 or do you think they really need to wait until they are 3? I dont' want ds to wreck it iykwim. I expect damage but not destruction lol
