All being well should be a grandma by the end of Summer. My son will be twenty one a few months later and I think outside of considerations around relationship length actually there are fewer reasons not to do this at twenty now than for a long while. Working for another five or ten years doesn’t bring the relative freedoms it once did. Jobs are unpredictable and the merits of being a youthful parent may yet be a great thing. Certainly I will get to be a livelier grandparent. His experiment will be more akin to the one my grandparents had living near family and using schools family has attended. I can’t see the negatives I might once have.
