My friend is 5 months pregnant. She currently has a cold and it is the second time during her pregnancy. Will that have an effect on the baby? Any natural remedies to avoid it?

As far as I know, catching a cold while pregnant doesn't pose any harmful effects on your baby--no matter how many times this happens. Just to be safe, though, see your doctor because colds can indicate that there's some sort of infection, especially if it's accompanied by a fever.
