Need some advice on what to do

So currently living with my in laws with my 17 month old and husband currently 39 weeks pregnant I'm due to be induced Monday .. we hit a rough patch about 10 months ago..i lost my job and so did my husband..he found a job a couple of weeks later but he isn't making enough right now for us to afford to live in our own place and I shortly found out I was pregnant and had awful morning sickness that almost had me hospitalized twice.. though we do pay our share living here and he is currently in school. My problem is every weekend without fail his brother and sister drop their kids off on my mil the whole weekend (now it's more often cause of school being out) don't get me wrong I love my niece and nephew being here they play amazingly with my daughter but am I wrong for me wanting them to keep their kids the first weekend after baby is born? I don't mind them coming over or anything but as far as staying the night Idk... I do everything around the house (cook every night, clean the whole house, and take care of my lo not complaining seeing as how I'm home all day yeah it would be nice if my mil helped but it's not a big deal) but I know after having my baby I'm not going to want to clean up after 3 kids and 3 adults all by myself..am I being selfish for asking them to keep their kids just this one weekend till we get settled in? Or should I just deal with it? My husband sees my side but he doesn't know how to go about saying something without making them mad or them thinking we just don't want the kids here..ill state again I have no problem with them being here..when his sister had her baby a couple of months ago we kept my nephew for about a week straight with no problems or complaints..i feel like they should understand but I know how sensitive they can be at times
