At 25 mph, which I would hope would be the speed limit on roads next to schools, slamming on the brakes even seconds before colliding with children can make an enormous difference in how fast the car is going when it hits the kid.
Speed is the factor in collisions (other than weight), and modern brakes are incredibly good.
Not to mention that the car, with it's 360 degree sensors, could safely and efficiently swerve around the children even faster than it can brake, as long as there's not a car right next to you in another lane -- and even if there is, hitting another car is far less dangerous to their life than hitting the children is to yours.
These things should be so much better than we are, since they're not limited by unidirectional binocular vision, but somehow they're largely just worse. Waymo is, at best, a bit better. On average.
