Do we baby children?

I think we baby children too much. Instead of conversing with them as little people, we treat them as if they wouldn't understand our 'adult talk'. It's as if we talk down to them. Children can engage in thoughtful conversation if you give them the chance and use language they understand. What a perfect time for children to learn and understand the importance of thoughtful conversation. Wouldn't this have a positive effect, all around, on their development?
