It can be tricky deciding whether or not to keep your child off school, nursery or playgroup when they're unwell.
There are government guidelines for schools and nurseries about health protection and managing specific infectious diseases at GOV.UK. These say when children should be kept off school and when they shouldn't.
Please take a look at the NHS guidance at the below link if you are unsure if your child is too ill for school.
Please remember, if your child is well enough to attend, but has an infection that could be passed on such as a cold sore or head lice then please commence treatment, send them to school and inform the class teacher who can inform other parents.
