I don't know that you can make that conclusion, that they will just be on their way. Go to netmums, /r/babybumps, or any other new mom group. This is an issue women have to face all the time. It causes a lot of conflict sometimes.

Now if your own experience has been to the contrary, I am happy for you and wish others also had that same courtesy extended to them during that time. But to think everyone will follow those rules, when women see time and time again that they are often NOT followed, is not acknowledging countless stories to the contrary.

My own mother is a great lady and I would love for her to be there a few weeks after I have a baby (I live on the opposite side of the world). To the point I would buy her a ticket and have her stay with me for a few weeks. If she lived close, I would have her visit right after. But you know what? I mentioned I didn't want my mom in labor and delivery with me, only my husband, and that we wanted it to just be us the first two weeks (besides brief visitors)....she lost her mind. Crying, screaming, just throwing a fit. My mil, who I love, had to be barred from her daughters room when she was delivering because the couple wanted privacy. She now babysits her grandkids and bad always had a great relationship with them and her kids, but this stuff makes people nuts. That is just the reality that a lot d people deal with.

Again, I am glad you have experienced differently, but many of us see this happen. You say no rational person would intrude, but a rational person wouldn't have this argument. When you deal with pregnant women, their labor and delivery and their recovery is on their terms. I know that isn't what a lot of people like to hear, but I just gave you sources you could type in "unwanted visitors" "in laws" "delivery room drama" and things like that into, and see differently. And this story is EXACTLY like those start out. Husband who wants to make his parents happy even at the expense of her pregnant wife.
