My DD is nearly 2 and attends nursery 3 days a week. So far this winter has been worse than the last and we are all ill pretty much all the time. We get a week off before the next bug comes along. DD has got a permanent snotty nose and has had a cough for nearly a month now.
I am pregnant so tend to pick up whatever DD has got as immune system a bit low.
Am not sure whether its because she goes to nursery or whether it would be just as bad if we were at toddler groups etc.
