Pittabre:
Thank you. OH was supposed to be looking after him in the morning and then MIL in the afternoon. I can't believe how ill OH seems and he won't let me take him to the GPs
ETA he is right it is flu and theres nothing they can do is there?
Definitely stay at home - it's the right thing to do.
If your OH has flu symptoms, I would say call the flu helpline or NHS Direct for advice, especially with a little one at home as well. It may be that there's nothing you can do, or that they wouldn't prescribe anything but better to check IMO. At my GP, there's a sign on the door telling people to go home if they have flu symptoms and call for advice, so visiting the GP probably wouldn't be the best plan.
Really hope both make a full recovery soon.
