I'm Gauri, co-founder at Toymail. We're building the first messaging platform for kids because most children under 10 do not have their own phone. Our challenges are in how to make messaging playful, secure, simple, and viral for young kids. Message me - I'd be happy to answer your questions.
Cool. I told my daughter who has a 2-year-old. She has a problem now that when she lets her kid play with her cellphone he disappears into bringing up kid videos. Based on available evidence he will do this forever.
