I think, at the end of the century we'll have a generation of parents and a generation of children who won't have had the deep satisfactions of being parents and being children in the way that they might have and are going to spend a lot of time fretting and worrying and being hovered over for nothing. The question isn't so much "What will happen in the long run?" but "What's happening to people's lives right now?"

We provide a secure, stable space for children to grow up in, so children will be able to take risks and have adventures and do things that are unexpected. If there isn't a risk that your children can fail, then you haven't succeeded as a parent.

Owning our past allows us to own our future.

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.

Babies and young children are like the research and development division of the human species, and we grown-ups are production and marketing.

Developmental scientists like me explore the basic science of learning by designing controlled experiments.

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.
