DD lives with XP. I live with a housemate/friend. Current guidance is that children can move between houses if their parents live separately.
XP has had new partner visiting/staying at the house on and off during lockdown. New partner apparently lives with a housemate. On XP's new partners last visit they brought their DD, who normally lives with XP's new partner's ex.
This seems like a LOT of mixing between households.
Generally I don't care what XP does but I feel this is unnecessarily putting DD/ myself and public health at risk... XP wasn't particularly upfront about any of this either, which puts me in an awkward position when I turn up to collect DD, quite clearly XP has visitors and I can't exactly turn away DD...
