Driving me insane

Both my parents and my SO parents are going to be first time grandparents when my daughter is (hopefully) born September 15th. My mother in law though is driving me beyond crazy! She can not have a conversation with me unless it's about the baby, or I will be having a conversation with someone and she'll cut in to talk about the baby! She will also text me randomly (mostly in the morning and I'm not even up yet) just to tell me how many days left. Don't get me wrong I am extremely excited for my first born but I don't want her to be the only thing I talk and converse about with everyone. Also I absolutely hate belly shots (there has been only two pictures of my belly I felt comfortable in)! She posted a picture of my belly (I didn't even realize she took) and posted it on social media. Then she text me "oh I posted a pic of your stomach." She didn't even ask! Also at my baby shower she kept making a scene how she's going to be a grandma for the first time, and I so badly wanted to be like "so is my mom!" She also made a present for her son (who just wanted to stop by at the shower not stay long) for him to open, all grandma onesies! Ugh Idk just going crazy here
