He's always been very shaky since he was born, he'll just at random times start shaking throughout his whole body but he's still very alert and doesn't seem at all affected by it. It's never worried me and I just took it as an unexplained little quirk he had. However recently the shaking has changed. He'll be laid on the floor one minute and then start shaking mainly in the arms and legs, his head arches back and his eyes kind of roll back however it only lasts around 3 to 4 seconds. I mentioned to my mum and sister that I was taking him to the GP and they basically said I was being silly, it's nothing (they've never seen it happen) my sister also mentioned that if it was serious it would last longer. AIBU to take him to the doctors? Could it be seizures? If not does anyone have any experience and know what it is? Thanks in advance x
