Help! How to plan visitors post birth

My husband and I are expecting in December and already his Mother In Law is asking when she can come stay with us.  She wants to be with us before the birth and after.  Tonight I sat down with my husband and talked to him about setting expectations now and talking to our families. I said that I'm fine if our parents want to come to the hospital to meet the baby but after that I don't think we should have visitors staying with us for 2 weeks.  After that his mom is welcome to stay.  He got really upset.  His mom lives in FL (we're in VT) and its a long trip for her so he thinks it's rude to not let her stay with us. She doesn't have money for a hotel so I said she is welcome to wait till after the baby is born to come visit or stay with her other son in NY and go back and forth. I tried to stress how hard this time will be and how important it is that we focus on the babies needs and our needs but he thinks I'm being selfish and trying to leave his mom out.  I tried to point out that I felt like he was worrying about his mothers needs before mine and the baby and he just kept saying that I wasn't caring about including our families in an important moment.  I only want to bond with my baby without worry if entertaining others and feeling stressed and vulnerable.  How did others handle visitors post birth?
