When Can My Child Go Back to Preschool After Being Sick? Sweden's 24- and 48-Hour Rules
Fever, vomiting or diarrhoea? Learn when children can return to preschool in Sweden, including the 24-hour fever and 48-hour stomach-bug guidance.
Your child seems completely fine.
They are running around the living room. They have requested snacks seventeen times.
Surely they can go back to preschool tomorrow?
Maybe.
Sweden has fairly clear guidance about when children should stay home after illness — especially after fever, vomiting and diarrhoea. Here is the parent-friendly version.
The most important rule
It is not only about whether your child still has symptoms.
Your child should also be well enough to manage a normal full day at preschool and take part in the usual activities — indoors and outdoors.
A child who technically has no fever but is exhausted, miserable or unable to join the group may still need another day at home.*1
Fever: usually 24 hours fever-free
1177 guidance states that children should stay home until they have been fever-free for at least 24 hours without fever-reducing medicine.*1
So if the fever disappears Monday morning, Tuesday morning may still be too early depending on timing. The child also needs to feel well enough for preschool.
Quick rule: fever → at least 24 hours fever-free, without medicine used to reduce the fever.
Vomiting or diarrhoea: 48 hours
This is the famous Swedish preschool rule.
For children in preschool or family daycare, 1177 says they can return when:
- they are eating normally again, and
- at least two full days have passed since the last vomiting or diarrhoea episode.*2,*3
That means 48 symptom-free hours after vomiting or diarrhoea caused by a stomach bug.
If your child last vomited Monday evening, Tuesday morning is definitely not preschool time. Neither is Wednesday morning.
Why is the rule stricter for preschool children?
1177 says children attending school should normally stay home for at least one day after recovery from a stomach bug, while preschool children should wait two days.*2
Younger children generally need more help with hygiene and have closer contact with each other.
What about a cold or cough?
A cough or runny nose does not automatically mean your child must stay home. The bigger question is: how does your child feel?
If they are energetic enough to take part in normal preschool activities, they may be able to return. If they are extremely tired, slept badly because of coughing or need much more care than usual, they should stay home.*1
Preschool is not a quiet recovery day — even if your child promises they will "just sit down". They probably will not.
What if my child is eating normally again?
For stomach illness, eating normally is part of the 1177 return guidance. But eating one banana and announcing "I'm fine!" does not cancel the 48-hour rule.
Both conditions matter: normal eating + 48 hours without vomiting or diarrhoea.
Does a healthy sibling need to stay home too?
Usually, healthy family members do not automatically have to stay home. However, during outbreaks a preschool may ask healthy siblings who attend the same preschool to stay home to reduce transmission.*2
What if the preschool has different rules?
Follow the preschool's instructions. 1177 provides general guidance, but municipalities and preschools can have local routines — particularly during outbreaks.*2
If you are unsure, just ask: "When can my child come back?" It is a much easier conversation than discovering at drop-off that everyone interprets "48 hours" differently.

And yes — this is where VAB comes in
If you need to stay home from work to care for your sick child, you may be able to use VAB — vård av barn, Sweden's temporary parental benefit for caring for a sick child.

One final rule of thumb
Ask yourself: could my child comfortably manage a normal preschool day today? Not: "could they technically survive it?"
There is a difference. And after a stomach bug, no amount of energy changes the 48-hour guidance.
