My daughter started watching this show from 4 months old. Now, at one year old, it's the ONLY show she'll watch attentively. Nothing makes her happier! The flat animations, bright colours and dark backgrounds seem to work wonders for young eyes. The first time she watched it, she was able to see and respond to Charlies smile with a smile or coo of her own. She's easily watched each episode hundreds of times... I know them all word for word now. We need a season 2 soon please, for my sanity more than anything else!
