My son will be 5 months old on the 11th. While he was sleeping on me one of his hands started lightly shaking in like a up and down motion it stopped and then started again. The second time I grabbed it and it continued to shake. He has done this before while asleep and when he wakes up usually during a stretch. I have grabbed it before and it has stopped once I did in the past. I have asked his doctor he said it was a immature nervous system and the hand should stop once I grab it. Well it didn’t stop this time and I’m freaking out! The doctor is supposed to call me soon and I have an apt to take him in tomorrow since they are already closed for the day. He has had a one hour eeg for possible infantile spasms and that came back normal but that was a while back. I was just wondering if any of your LO’s did this and if so does it always stop when u grab the area?
