One day our kids are perfectly healthy and then, the next thing we know, they are sick. But how do we know when they are too ill to go to school or nursery? DI-VE has the answers.

Fever - If your child is over the age of four months and has a temperature of over 38°C, then school is a definite no-no. Not only are feverous kids considered contagious, they will also not be in the mood for participating in class or learning. Wait until your child has been fever-free for at least 24 hours before sending them to school. For kids who are four months or under, contact your doctor at the slightest sign of a fever.

Vomiting - Being sick is a telltale that something’s wrong. If the kid’s only vomited once in 24 hours then there’s no need to worry, but be wary if it happens more than that. Check for signs of dehydration (passing urine less often; dark yellow wee) and phone the doctor.

Diarrhoea - If your kid’s faeces is very watery and they are going to the loo often, keep them off school. If your baby’s poo is so watery that it leaks out of his/her nappy, then the same applies. Make sure you monitor them and that they are not dehydrated. Don’t worry too much if their stools are only slightly loose, however, some kids suffer from diarrhoea simply because they have too much juice!

Sore Throat - If this is accompanied by swollen glands, fever, or a stomach-ache then avoid school completely. If it’s just a bit irritated and only accompanied by a runny nose and no fever, then it’s most likely okay to send them to school.

Stomach-ache - Unless the stomach-ache is related to fever or diarrhoea, then there is a big chance it’s just nerves or mild constipation. The major sign to look for is relatively simple: are they still jolly and playful or are they feeling down? If the stomach-ache worsens make sure you visit a doctor ASAP as this may be a sign of appendicitis or severe constipation.

Colds - If your child is feeling lethargic, has a runny nose, a cough, and a fever, then obviously he should stay at home. A runny nose on its own, however, should not put you off sending them to school.
