IMO, i dont think the principal will go arnd telling the teachers you complain, she will only feedback to them regarding such a case.
n the principal shld be understanding enough towards your concerns for your child n take appropriate measures.
n i dont think it is appropriate to ask for a claim on bills n such.
when you place your son in the infant care, you shld be prepared that it will happen.
even if your son's infant class is seperated in from the other classes, like mentioned, they r ALL still in a enclosed air con area, so the virus n germs will still spread.
this is something you cannot avoid. as said, you only suspect the reason why your son contracted HFMD, means you do not know the real reason.
plus, maybe your son contracted it frm somewhere else?
i believe such things cant be avoided.
the other time the doc diagnosed pin with hfmd, n she was absent from sch for 2 weeks, til now, not even sure if it was HFMD, cos 3 diff doc diagnose (2 were relief docs) n end up i went to a diff clinic (skin specialist) n the doc say it was allergy reaction..but in the first few days, pin really had those ulcers in her mouth...so til now i just take it as she did kena HFMD but a mild one.
cant be i tell the doc his relief doc diagnose wrongly n return me my 2 weeks leave, plus pin's 2 weeks sch fees n my medical fees right??
i think it is the "risks" you need to take if you put your son in CC...
