My 7 year old son had been poorly on and off for more than a month. Each time he has some pretty nasty things like kidney infection, scarlet fever and now chicken pox. Each episode he had needed paracetamol for around 4 or 5 dsys( I have tried to use sparingly so not the full 4 doses each day) but each time he has a week free before he has needed them again. Can this be damaging or would a week inbetween be enough to recover? Sorry I am very tired at the moment and suddenly looked our bottle of calpol and mentally working out how much he has needed recently.
