You will probably find when your child goes to playgroup or nursery that they get lots of coughs, colds and sniffles. There are some good things about this though as it helps the body build up a natural immune system.
Flu can be more serious than a cold and leave your child feeling quite unwell. Flu tends to come on more suddenly and severely than a cold. Your child may feel achy and uncomfortable, and be ill for a week or more.
Most bugs will run their course without doing any real harm because they will get better on their own. An annual nasal spray flu vaccine is available for all children aged two and three as part of the NHS Childhood Vaccination Programme. Ask your Health Visitor.
