Help please, I am really concerned. My little one is 1 and a half and he's been having an unusual behaviour, like a shake of the arms, hands and head for a few seconds. There's no eye rolling or loss of consciousness. He stops whatever he is doing when he has the shakes which last a few seconds, then continues as normal. He seems to have no fever and apart from these shakes he behaves normally, he runs around, he's his usual chatty self (maybe with the exception of this morning when he seemed very tired before the episode happened).
It happened 4 times today, his Gran noticed it a few days ago happening once as well, I noticed something similar every now and then (not often) in the past months, no obvious pattern.
When it happened before (quite rarely) he was playing or tensing over a toy and we attributed it to over excitement or being annoyed at something he was playing with. But today felt different because it happened in unusual circumstances, he wasn't playing, three times he was in the high chair eating, and one time he was outside in the buggy while we were in a coffee shop. The friend that I was with also found it unusual so it wasn't just me imagining it. It looked like the kind of shiver one might have from a cold.
I have an urgent GP appointment this afternoon but I am really miserable and concerned and I could appreciate if anyone who experienced smth like this could write me a few words. What can this be? :-( Thank you X
