So as of Saturday I, as a single adult household with DC under 18 can bubble with another household. I choose DP.
Children can go between parents still and still bubble with another household.
DP has DC who go between him and their mum - so therefore 3 households.
My DC will be seeing their dad - so now 4 households.
He is a single adult and will no doubt choose to bubble with his girlfriend - 5 households.
Her children have been seeing their dad - so 6 households. No idea of their dads situation, but if he is a single adult he may choose to bubble with a partner/girlfriend therefore increasing this even more.
Pretty sure this isn't what the government intended, however all perfectly legal from Saturday - I'm not complaining as can't wait to see DP, but I have got this right, haven't I??
