It can sometimes feel as though your child has only just recovered before the next lurgy arrives. But how much illness is normal and what can we do to limit the spread?

The Traitors series three winner Leanne Quigley discusses the extra worry she feels when her twin sons, who were born prematurely and have ongoing health issues, become unwell.

GP, TV doctor and author Dr Nighat Arif explains why common illnesses spread so easily and shares advice on prevention, warning signs and when to seek medical help.
