I've changed some details here.
DD5 went to her dad's yesterday. His girlfriend has tested positive for Covid girlfriend is very involved with DD so lots of close contact.
I've suggested he keep DD, and we wait it out. If on day 5 DD is testing negative, then he take DD to school and then ill pick her up and she will come home. This is also the advice from 119.
His reason for wanting her to come home tomorrow as normal is that he will get "stressed" and that DD will have to watch her brother and sister go home. (That's their mums choice, none of my business)
Im extremely vulnerable and was a shielder. I've had pneumonia, a heart attack and have high blood pressure. I've also got numerous mental health disorders which have lead to me being hospitalised in a psych ward.
So me catching it would be horrendous in all ways. And I am the sole parent of another child.
AIBU?
