Ben can go out once his 10 days are up he doesn’t have to stay in till hers are up. It’s such a weird system tbh. 4 of our family have had it . Son 1 got it first then son 2 got it on day 5 of son 1,then I got it on day 8 of son 2 then my husband got it day 9 of me. All of us were allowed out after our 10th day of contracting it. The only ones that couldn’t go out are the ones that came into contact with us but had no symptoms and tested negative so my other 4 kids had to keep restarting their isolation each time and me and the hubby are double vaccinated too yet I had it worse than anyone in the house , it’s bloody stupid as the system makes no sense.
