Driving me insane

I'm now a week "over due" (even though I'm a strong believer in due dates are a guess and not an eviction notice) 

My MIL is driving me insane!!! And the sad part is she knows it but doesn't seem to care. Every single day this woman calls me and text me to see if we've had our baby yet and how I'm doing, if anything has changed, if I've had any contractions, etc. she will not leave me alone, she has also expressed her feelings on how she is not ok with our decisions on our birth plan and when we will have visitors.

We are having a full on natural birth at baby and co. The only ones there will be my support team, which include my partner, midwife and doula. That is it! No family or friends will be there for the birth or visiting after our little girl arrives. My man and I have talked about this ALOT and we want our very important bonding time. 

His mom on the other hand believes that she is also extremely important during this bonding time and a necessity to our babies first moments of the outside world. We have expressed to her that we are not even making phone calls or text out to anyone when I go into labor and we will let family know when she arrives when we are good and ready AFTER we get home and are settled. As far as visiting, we aren't welcoming anyone until a few days after, again, when we are good and ready. 

MIL says that she WILL be at the house as soon as we let her know when we are in labor to help and she will be there for the birth and come home with us after. 

Obviously this is NOT happening and she is now making it to where she will not be contacted til we are ready for her visit. We know this will create problems and she will be very upset, but her not respecting what we want has pushed us to this point. 

Any advice?
