He had drank some of this water - there was nothing else wrong with him. Also, this is a child that has a strong memory and relate everything back to you verbatim and if you tell a story and don't relay it exactly like it was said he will correct you. Then noticed about 3 weeks ago that he was having memory problems, even with names, so much so that it was very disturbing to us. After finding out that he has been spending a lot of time in the hot tub with his mother, we look up dangers and saw that brain damage could be one and that there is also the chance of getting legionnaries disease, etc. I am against a child/toddler being in a hot tub - especially a public hot tub at an apartment where his mother is putting him in. I have heard of many dangers associated with children and hot tubs. Am I not suppose to be concerned with this?
I agree with your concern about unhygienic condition of community hot-tub of an apartment. Certainly a five year old cannot be having general immunity, which is just starting to get built up, to avoid catching infections of all sorts repeatedly.
Children should best be bathed in their own quota of bath-water, and even family members should not have mixed bath especially in a tub.
Sometimes such tub water is chlorinated and dissolved chlorine is also bad for respiratory and nervous systems.
