Argggh. I thought that once you've had your cold and recovered from it, you will be immune from it for at least some time. My kids have been sick in the last month and have barely recovered, but it appears that the elder one is coughing and having the sniffles. Again. Which she seems to have passed on to me. Again. I am guessing that my body has recovered from a certain strain of the flu virus, and now a different strain is in my system. I will do what I can to minimise the effects- which means the usual loading up of vitamins and drinking plenty of fluids and fruit juices.
