Postpartum boundaries struggle

My husband won’t set boundaries with his family over seeing our newborn. She is 3 weeks old today and we have had people visit us all but 2 days since she came home from the hospital. I am an introvert naturally but especially so with a newborn and extreme postpartum anxiety. He has a large family while I have 3 family members so he doesn’t want to hurt anyone’s feelings by telling them no when they ask to see her.

My mom will occasionally stop by for an hour or so to help me, but he feels that if my mom comes by then his mom will be jealous and should be able to come too. Idk how to communicate to him how badly I’m struggling with this, he just sees it as me not being fair and not wanting to see his family as much as my own. I honestly don’t want to see anyone. Meanwhile, we had 15 of his family members over for 5 hours the other day.

I’m losing it and we’re fighting constantly over this but we’re also obviously both people pleasers and idk how to change this dynamic. I’m fine with saying no to my family but it’s awkward to have to speak up to his when he doesn’t even do it.

Please offer any advice that worked for you postpartum or how you think I could communicate this better to my husband. I feel like he truly doesn’t get all of the physical and mental things I’m dealing with and just tells me he wants things to be “fair.”
