Thank you for your query.
I can understand your concern.
Bleach fumes are dangerous.
They cause severe irritation to the eyes and skin.
They might cause respiratory problems and cough
Carefully observe the child and bathe the child and wash the eyes.
Consult your doctor about medications if the problem persists.
If you have any further queries you are free to consult me.
Hope this answers your query.
Wishing a speedy recovery.
Have a nice day.
