Found out today that my MIL, FIL and all 4  of my husbands siblings have all take off work/school the week my twins will be born. They live down the street and have decided that they all want to be here during the day to spend time with the babies. My mom will be staying with us the first few days to help. So I don't want or need all these extra (very loud drinkers and smokers) here all the time! Two of three of them coming for an hour or so is fine... But not just camping out all day in my studio apartment... We are first time parents and I have to have a csection. So it's already going to be crazy. How do I nicely say they can't be here all the time and to call to see if it's a good time for them to come before showing up? Or am I just being rude?
