at home. She doesn't get to do fun things at home when she stays home sick and we only keep her home if she has obvious symptoms of something that the school would send her home for like a fever, vomiting, etc etc. We don't keep her home because of things that we can't confirm like "leg pain".

She would be perfectly happy staying at home in bed all day. I suppose if we stripped her room down to the studs so that there was literally nothing to do, that might work.
