<s>[INST] My son is 5 and just spiked a fever or 102.6. Every 2/3 minutes (for the last hour) he jerks in his sleep causing him to gasp and sit up really quickly. I have 4 kids and have dealt with my fair share of sickness but have never seen this. Is this normal??? [/INST] Most fevers in child Chat Doctor.  Although febrile convulsions can occur in case of high rise of temperature, going by your description it rather seems to be benign sleep myoclonus which is not harmful, and you need not be concerned. It is normal and can occur in sleep. But I would strongly insist you to visit a pediatrician and to get the child assessed about the cause of fever so that it can be managed accordingly. </s>
