Short piece that recommends gentleness and trying to get ahead of the stressful moment (which frankly seems a bit idealized; I'd love to be able to see the future, but I'm not sure that's easy/reliable). They do make the point that:

Most of what helps a child “have a go” is built in to the everyday conversations at home, not on the morning of the event. It’s about gently setting expectations: that we don’t always have to win, be the best, or get it right, and that’s okay.

And end with:

The goal is a child who learns, over time and in small steps, that they can do hard things, and that being different from the child next to them is okay and a normal part of life.
