Do you have health insurance? I'm a paranoid worrier who likes to overplan, so I thought about this a lot... and that's what it boiled down to for us. Once the initial surgery is done (and the immediate aftermath was handled by Brassard's nurses) and she was back in the US, most of the possible complications are largely in line with what cis women may also experience. Tears, infections, even fistula repair are all familiar ground for doctors who deal with women and especially childbirth, and any US hospital with competent surgeons ought to be able to manage it for no more than the usual copays/deductibles.
(A purely aesthetic revision to get the looks back to optimal post-complications is something a GRS surgeon *might* be necessary for, but that can also be saved up for, as it's elective. And even in that case, a plastic surgeon who specializes in undoing the damage from childbirth might be able to handle minor revisions.)
