Can't give too much background detail, but imagine this. You have come home from hospital with your baby and you are expecting a midwife to visit you. Maybe you are anxious parent, maybe you are having problems feeding. You get a phone call cancelling your home visit and putting it off until the next day. Meanwhile a midwife who feels perfectly well has been sent home from work because she has a streaming cold - well past the sneezy/infectious stage (besides which her hand hygiene is impeccable and she ALWAYS catches it and bins it) because "it will cause parents to be anxious".
Newborns rarely if ever get colds in the same way adults do, so not much chance of passing it to a baby. I think parents would rather the midwife came with her cold than their visit be cancelled. AIBU?
