DS (6yo) has been sick the last three weekends running and I'm getting really worried. He is sick in the middle of the night and then fine in the morning, eating normally etc. He hasn't eaten the same thing each time, haven't done the same things, he isn't worried about anything, no allergies... there's really no explanation for it. There are no sickness bugs going round at school either.
We're going to the GP tommorrow but I'm getting really worried...
