I am hearing, you want to minimize future problems. I say, dont borrow trouble. Like thinking, what if she wants five more kids? Not to give the evil eye, but there were some issues with this one, right? She had to quit early? I would wait and find out for sure what her plans are. Maybe this is her first and last? Maybe i missed that you already had this discussion with her. I dont think that discussion would be crossing boundaries. Maybe she doesnt know yet.
