I just want to vent a little

My baby is 11 days old and everything has been great for the most part but I’ve already been kind of struggling emotionally with adjusting to being a mom of 2 and just feeling lonely. My partner has been doing a great job at checking on me and supporting me but his mom is calling multiple times a day and is pushy asking about my baby. It’s her first grandbaby so I know she is excited but she never asks if I’m okay or I feel like takes into consideration the fact that she has a mom who just went through childbirth to bring her here. She acts like she is entitled to my baby constantly asking for pictures so she can post them to her facebook. I told my boyfriend how that bothers me because we don’t want her posted to social media a lot and he told her that she can’t post any more pictures to facebook except for on occasion which I am fine with but she is still always calling asking to see her and calling her “my baby” and it just really bothers me because she is not anyone’s baby but mine and they don’t even care to check on me but want to act entitled to my baby.
