Hi, I amnot sure if my 31/2 yr old son swollowed a very small amount of toilet bowl cleaner. Some cleaner was accidnetly left on the rim of the toilet and he sat on it. And may have put his hand on it and then put that hand in his mouth. He didnot look like he tasted anything bad. I am just a little worried. he seems fine. It has been 5 hrs. I gave him about 2 cups of water and has peeed quite a few times. What else should I look for?
Hello. I just read through your question. A trace amount of toilet cleaner left on the rim of the bowl is not nearly enough to be toxic.  You did the right thing by giving him water as a precaution. However, you do not have to worry that anything bad will happen. He didn't ingest enough to be adversely affected.
