It is okay to let the child sleep. You must keep an eye on the child and make sure that the child sleeps naturally.
You need to control the childs condition and wake the child up every 2 or 3 hour to make sure that the child is okay.
The child needs to react naturally to your touch while it is sleeping.
If you have any worries you can contact the emergency department in the first 24 hours after your discharge.
Later than 24 hours after your discharge you can contact your general practitioner or the emergency doctor service – phone 70 11 31 31.
If the child can not be comforted you also need to contact the emergency department (in the first 24 hours) or your general practitioner or the emergency doctor service.
Be aware that babys and small children can not tell if they have a strong headache or nausea.
