I've been noticing that my 7 month old boy keeps getting these muscle twitches/spasms of the neck that last about 10 seconds. It almost seems like he has torettes. His head kinda moves from side to side. Sometimes he loses grip of his perch and flies to where i am sitting. It seems to happen at least once a day out of no where. Is this him having a seizure? I sure hope not Please help!
