A few months after I'd just got out of hospital with my baby we were exposed to covid because OH nor his ex bothered to test DSC after DSC1 was identified as a close contact. DSC1 was eventually tested at my behest and was positive but luckily we managed to evade getting it. The other DSC remained negative too.
I was quite cross with OH and his ex about it, understandably I think, but all was fine in the end.
I told OH from then onwards if any of DSC had covid symptoms or are identified as a close contact he must test them before they come in. He agreed. I said I would be adopting the same rule with our DC, so if ours had any covid symptoms or were a close contact I would test them before exposing DSC as it's only fair.
Fast forward to now DSC have just arrived and 2 of the 3 have a hacking cough, the only one who isn't ill is the one who tested positive for covid at the end of last year.
The first I know about it is when they come in and within 5 minutes one is coughing and says he's been "seriously" unwell since Monday.
OH claims it's the first he's heard about it 
Now I know many people aren't bothered about covid anymore and the rules are set to change etc but it's something that still bothers me as I am vulnerable and the vaccines don't offer complete protection.
We don't have any tests left over so will now need to get some for my peace of mind.
AIBU to be upset with OH?
