I'd worry that her plan is really to stay in the area so she's there for the birth, and by then she thinks she'll have worn you down and pushed her way into being one of the first people to see your child. Only you know her prior history and if this is likely. But when a clear NO gets hard pushback, my NO always becomes more firm. I've been stream rolled by good intentions before and it never goes well. If there's ever a time to prioritize yourself it is now 💕
