Had an awful winter here over about 2 months starting with Christmas. Chief culprit was the 3 year old bringing bugs home from nursery class in the local primary school. He did this twice. The first time it swept around the whole family after the Christmas gathering. Two had antibiotics for chest infections as the cough element just would not clear up. Then after a couple of weeks, it struck again. Not quite as severely but my H was the worst hit each time. Age I suppose as he took weeks to shake things off unlike when he was younger. Luckily, the baby ( who is five and a half months now, time flies!) seemed to deal with things remarkably well. By now she has had about 4 bugs so her immune system must be gathering strength!
