My 6 week old who wss born at 36 weeks has had a few leg jerks. Is this normal? . On researching same i realise this is ankle clonus. On doing the foot test it jerks for a few seconds but i note it is considered abnormal anything more than 10 beats. Can anyone tell me what is regarded as a beat? Is this a second or q jerk? Im going to bring it up at 6 week review but starting to get a bit worried.
