UGH. Who wants to entertain guests for 6 weeks straight, let alone while you're 41 weeks pregnant or after you've had a baby. That would be really irritating! If you want them around but not in your face, tell them to stay in a motel. That's not unreasonable. You're going to have enough going on without having to deal with a house full of well-meaning but probably totally overbearing and annoying visitors, while trying to manage a newborn, baby blues etc. Plus who do you choose?!?!?! Yes she's your mum but your MIL is your partners mum, who honestly is just as equal in this situation. She's a grandmother too.

The only exceptionwould be if you had a REALLY awesome family member who you knew would be supportive, helpful, and knew their place in your new little family. Then I'd let them stay, cos sometimes you do want/need the help in that first stage, even if it is to just go have a shower!

Just a question though, are any of them going to be a birth partner? Is that what your mum is assuming/expecting?
