Just want to know if I'm overreacting here.
I agreed to babysit a friend's baby for an hour last week so she could run an errand. They came to my house and I kept baby in the sling throughout (baby's happy place apparently).
Three days later I got a call from this friend who had tested positive for covid. The following day I started feeling unwell, a couple of days after that my DC developed a temperature and my DH also started feeling unwell. We got tests and are currently all covid positive.
The friend had said her symptoms started the night after I babysat. So two days before she told me about the test result. I'd seen her DH one of the residential streets here wearing a mask the day after I babysat (so the day of the night her symptoms started) which I remember thinking was odd as literally nobody else was on the road except for me. But maybe a coincidence or he always wears it - as she said symptoms started that night.
If she'd told me when her symptoms had started I would have been way more careful around my DC and DH but as I had no symptoms myself and was unaware of hers, nothing changed. Still cuddling and kissing my two year old, sharing cutlery at dinner, not wiping down handles indoors etc. My DH continued to go to work and saw friends (they all have to self isolate now and one feels unwell). Luckily I knew about the result before going into work that weekend and before seeing my high risk family members. By sheer luck I'd had to cancel a play date the day after I babysat.
AIBU to be very angry that I could have prevented infecting my family?
