Re: If they self-wean before 12 months?
I think the reason there's no answer here is that... There's just no answer! What a mama does when her baby self-weans at less than a year is very individual. Some mamas fight it, some mamas accept it. Some succeed in bringing their babies back to the breast, some fail. Some are very comfortable using formula until a year, others would prefer to offer solids or the not-recommended animal milk. What you do, what your baby does... That's going to be as individual as the both of you are.
