A very difficult question of great concern.
There are many variables.
Type of ice : Crystal or the nasty refrozen slush on 1/2" of ice ?
The type of freeze - thaw cycles, since any ice formed.
Rainfall, yikes.
The size of holes in the area.
I'm sure you care for your child more than a fish many times over.
If you "Proof" the ice, it'll probably be fine, though it also depends of the child's activity level.
Good luck and stay safe.
