GUESTS AFTER BIRTH?

So my family has always been about space and they’re not clingy or not overwhelming... my boyfriends family is the complete opposite.

Him & I were talking about people staying after our daughter is born. I want to come home to an empty house and really take this time to ourselves to adjust and bond with her, just the 3 of us. His grandmother TOLD US she would be staying with us (his family lives in Oklahoma & we live in DFW, Texas and one of his aunts lives 10 min away from us where his mom and grandma usually stay when they come). I don’t want her to stay, we live in a one bedroom apartment.... if she were to stay then so would his mom, little sister & little brother. He asked me how I could be against it when I don’t even know how I’ll be feeling after she’s here. I told him I’m already overwhelmed by everything already and I’d like for them to stay somewhere else like his aunts house. He said “you’re really going to tell my mom she can’t stay?” YES!!! I really want to breastfeed and not worry about his mom or his grandma trying to tell me what to do. His grandma literally has no filter and thinks it’s all her way or no way. He says “they won’t stay long” I only get 6 weeks of maternity leave off, it’s not like a I get months.

How do I get him to be on my side about this?! How do I approach it when the time comes in 10 weeks?! I’m annoyed already just thinking about them staying. Plz help. Again we live in a one bedroom apartment. It’s big for him and I but definitely not big enough for 4 additional people.

This is the same mother that just said she hopes my daughter comes end of March. My due date is April 23rd.... like seriously?!?!
