Your hubby is being a di@k, I can't believe he won't support you with this.
You are being more than reasonable. Having a new bubba is a stressful time. Your days and nights are topsey turvey, bf'ing can be difficult to establish.
I was also stressed about having 'guests.' I didn't know how I was going to cope with a new bubba and I wanted privacy and freedom to deal with it. To sleep in until lunchtime if I needed to. To not cook. To let the housework slide. To have my boobs flopping around uncovered. My fears were made worse by what my parents did to my sister with her first bub. Without invitation 1 week
Before her due date they drove 8 hours to her house with suitcases and stayed for 2 weeks! My sister was so stressed and pi$$ed off. My parents are lazy and annoying and she just wanted to labor in privacy.
--- so, from when I was about 3 months pregnant I told everyone: no overnight guests 4 weeks before and 4 weeks after bub. The exception being my parents could stay at my house while I was in hospital but had to be gone when I was out. My dad kept dropping hints, I stood firm. Then he tried the old "I've got an appointment in town" which just happened to be a few days before my due date. I said "well you have a problem then, because we're not having guests 4 weeks before and 4 weeks after bubs due date." My father chucked a mini tanty but i stood firm. They booked a hotel.
I am so glad I did that.
My advice: tell your hubby off for not supporting you then give his parents a call and explain no overnight house guests. If you're afraid of offending them try this: "it's not you it's me. I have a feeling things are going to be noisy, chaotic and uncertain within the first few weeks. I'm afraid it won't be a very good situation for any house guests."
Failing that tell them to get effed
