Yes, it's called Febrile Fit if I recall. My eldest daughter kena before when she was like 5 years old during a wedding. Had fever and she was resting while drinking milk and left for awhile only. Came back and saw milk bottle on the floor and she like stiff and mouth with foams bit. Scary shit for a parent.

Lucky had many nurse n docs in family. They cool her down, wipe with water, loosen clothes before she regain back normal. Then rushed to hospital. Still remember the short journey seem like took forever.

Hope TS kid get better soon.
