I pick up my friends 2 dd’s from school twice a week while she’s at work, single parent in a support bubble with her folks who do the other 3 days.
Reading the rules it looks like it’s within them for me to keep doing this as you can have both a childcare and a support bubble ( we won’t be using it as an excuse to socialise, it will literally just be childcare, though quite handy as our children are v close). I haven’t misread it have I?
