If you live with other adults, including if your carer lives with you, you can form a support bubble with one single adult household.
Once again, they should not be in a support bubble with anyone else.
If you share custody of your children with someone you don’t live with, then you can form a support bubble with another household other than the one your child’s other parent lives in.
If you’re not a single adult household, you can form a support bubble with a single adult household other than the one that includes your child’s other parent.
