Human development isn't a race; it's not who gets anywhere first! Character takes seasoning and really isn't seen until we're adults. I can probably drum up hundreds of kids who rolled over onto their stomachs before all their peers-and who ended up in jail. Don't worry about other kids' progress compared to yours, and don't gloat if your kid's progress seems advanced. It doesn't matter (91).
