He has some sort of vomiting bug. I cannot stand sick
Since he started being sick I have washed towels and door handles and had a generally good clean to try and prevent anyone else getting it. DP is on the top floor with access to a personal bathroom and the spare bedroom. WIBU to insist that he does not descend the staircase until he is in fine fettle once more? I'll chuck some snacks up there occasionally, I suppose.
