IMO it doesn't have to make anything worse. Hormones make everyone act differently. I would be more concerned about memories and what ones you have, if they have any connections to this type of event, and how you have worked through/with them until now. There are many great moms and dads out there who have PTSD, and because of it they might be a bit overprotective, but they can relish the opportunity to love their own child, as we all do.

I hope you get your wish, whichever you want.
