So we had it all worked out (or so I thought) IL's expressed a desire to be here when our baby was born. Fine come when I'm in labor, visit while I'm at the hospital and then go away for a while. (They live 4/5 hours away) My mom was coming for the same amount of time + 1 day to get me home and settled. (she's 6 hours away). Then no one for two weeks (the amount of time my husband is taking off to stay home) so we can get to know our baby and bond and get used to his needs/routines. 
Then....mis communication with SIL leads to phone call about "what do you mean we can' come for two weeks" they though we were taking back the hospital part. No no, original plan still in place. IL's "okay just tell us what you want us to do"
Now as of last night (and two weeks before I"m due I might add) they no longer want to come at the birth time, they want to come on the following weekend. Which is exactly what I want to avoid,people being in our at home bonding time that I think is important for myself my husband and our baby. when we said no...a tantrum ensued. With me trying to guess what was being said on the other end of the phone call--it's now a big fat mess and i'm so sick of them I could scream. They are making the birth my my and my husbands baby all about them and I honestly hate them for it. 
In all honesty (I am for real asking here) is it too much to just want two weeks before we are inundated with (typically dramatic) family members? 
My husband thinks my wanting those two weeks is not reasonable, but I don't see the problem. Anyone? 
                 
                
Re: Family Visits (mostly in-laws)
Very sneaky, OP
Also, I'd rather have a drive by ask about issues with in-laws than have us question the state of their cervix.
Eta: and overnight visitors help with night time crying babies
I will say what I say on every single one of these types of posts...people can't make something about them unless you allow it. You and your DH are grown ups. If you made a decision and are comfortable with it, there does not need to be a discussion. I don't care if they rant and rave and drive by your house honking their car horns. A simple 'this is our decision and we expect everyone to respect our wishes' can pretty quickly end most discussions. If they push back, again 'we already shared our decision with you and we aren't interested in discussing it any further.' and repeat, repeat, repeat, as needed. Your in laws are adults...you are adults. You most likely wouldn't tolerate that type of behavior toward you and your new family from an acquaintance. To me, it's no different just because they are family. If they don't feel a need to provide a certain level of respect for you, then in my mind, you are under no obligation to provide any elevated level of respect for them. No need to be rude or fly off the handle, just calmly explain your position and leave it at that.
I just re-read and saw your husband and you aren't on the same page. Step one: get on the same page. Then go ahead and follow the instructions above!
damn i was all.. and she was all.. what the hell just happened?
Now, I'm on mobile and can't see your post history. But let me ask you this...how supportive have you been to other people? When you say "I thought the point of these websites was to be helpful and supportive," do you just mean you deserve support, but haven't given any?
I allowed family visitors at the hospital, and had an open door policy when we got home. I just asked that people let me know when they were coming so I had a heads up and if I wasn't feeling up to it I would ask them to come another time.
It was nice to have people around, and it seemed like most traffic was during the weekend vs. during the week when most people are at work so that allowed for plenty of time to bond.
But its a personal decision, and hopefully you and DH are on the same page, and those you inform of your decisions will respect it.
