Thank you for your query on Healthcare Magic.
Usually the toilet cleaners contain acids which are very dangerous if they are consumed or touched.
The manifestations will be oral ulcers, refusal of feed, drooling
of saliva, vomitings.
Even though child is active without any symptoms at present look for the above symptoms.
And I advise you to consult Emergency for the examination of child oral cavity and to assess the features of poisoning
Keep drugs, chemical out off reach of children.
Hope I have answered your query.
