What teenagers want most of all are social rewards, especially the respect of their peers.

You read a bunch of books and you get a bunch of how-tos, and you take a bunch of classes and you learn a bunch of techniques. You set yourself goals and benchmarks. I think people have imported that into their experience of taking care of children.

We know that kids who grow up in an environment of warmth and support will thrive and function in whatever environment they find themselves. What we need to do is to do more to help poor kids have such an environment.

I'm afraid the parenting advice to come out of developmental psychology is very boring: pay attention to your kids and love them.

The youngest children have a great capacity for empathy and altruism. There's a recent study that shows even 14-month-olds will climb across a bunch of cushions and go across a room to give you a pen if you drop one.

All of us gardeners know that nothing comes out the way you planned. It's a different garden every year, and it's always sort of different from what you were thinking when you began. What it really means to be a good gardener is to work hard to produce an ecosystem that will have enough diversity, enough possibilities, so it's robust, and it's resilient, and it can change when the seasons change. And that kind of robust, unexpected, variable, messy system - that's what you want to create when you're having children, too.

Teaching is a very effective way to get children to learn something specific - this tube squeaks, say, or a squish then a press then a pull causes the music to play. But it also makes children less likely to discover unexpected information and to draw unexpected conclusions.
