If you’re a parent, you’ll know that babies and little children get sick really often. On average, children get at least eight colds a year.As your child discovers the world around them, they come into contact with lots of different microorganisms, many of which can cause infection. When they’re young, their immune system doesn’t have the antibodies to fight off these infections. This means they’re likely to get symptoms like coughing, a runny or blocked nose, fever, sore throats, and rashes fairly often.The good news is that all these early infections help to build up your child’s immune system. As they get older, they won’t get ill so frequently and when they do the symptoms won’t be as bad.In short, most of the time a cough is nothing to worry about. But if you’re worried, we’ve put together a guide to coughs in children, including when to see a doctor.What are some common causes of coughs in children?Lots of different things can cause a cough in children.
