Do we even know that the child was injured? All I've seen anyone officially claim is that the Waymo made contact, the kid fell over, then stood up and walked to the side of the road. Assuming the Waymo was still braking hard, 6mph means it was about 1/4s and about 30cm from reaching a full stop, so it could be a very minor incident we're talking about here.

I'm not aware of any statistics for how often children come into contact with human-driven cars.

Here is what I think we know, in table form:

                 |               | Injuries | Undesired  |
                 | Miles         |    to    | Pedestrian | Feline
                 | Driven        | Children | Contacts   | Fatalities
  +--------------+---------------+----------+------------+------------
  | U.S. Drivers | ~3e12         |  ~7000   |     ?      |     ?
  |--------------+---------------+----------+------------|------------
  | Waymo        | 100e6 - 200e6 |    0*    |     1      |     1
  +--------------+---------------+----------+------------+------------

* for all we can tell, this incident doesn't rise to the level of injury that results in a reporting event that is captured in the 7,000 number.
