The family was recently sleeping together in a hotel room and I noticed dd was shuddering in a kind of jerky way. She was asleep but the shuddering repeatedly woke her up (but she was still very drowsy and wasn't really aware what was happening) and then she went straight back to sleep. It happened every couple of minutes for several hours. It's not the first time this has happened. It happened when she was a very young baby but now I'm wondering how much it happens when we're not there to see it. I've recently read that there are some forms of epilepsy that only happen at night and am now worried this is what she's got. Any expereince or advice out there?
