Yeah... no help here, either (when I had food posioning, I literally strapped my son in the carseat and we lived in the bathroom for 2 days).
When it's NOT that severe... we watch a LOT of movies. And my son helps me (gets drinks, helps with chores, etc.) since he was very little. Helps teach empathy. He doesn't GET to just carry on with his usual life when I'm sick. When I'm sick, he helps.
