work in the garden. it is 8x5 and only about 4 inches deep.

Dummy is right.

Your son is much too young to be left with that pool unsupervised... a
child can drown in less than 2 inches of water. Get rid of that pool
now... before you wish you did. Your child will have more fun cooling
off with a small lawn sprinkler, the water will be clean and at the
same time it'll water your lawn... and no one has been known to drown
from a lawn sprinkler.
