Am I wrong to think about not telling my mom when my son is here? I feel like I have to beg her to talk to me recently. She doesn't answer my calls or come visit me. Doesn't ask how I'm doing nothing. When L&D told me I was in labor I told her and she just told me she doesn't have time for this now and she will talk to me tomorrow because she's going on vacation. Well I tried calling her but of course she never answered or called back. It's just kinda hurtful that if I was my older sister she would of cancelled everything to be there for her but can't be there for my first child. I'm just to the point that I'm done. I have her on the list to be in the room with me when I deliver but she's already told one of my sisters that she doesn't wanna be in there with me. I'm the youngest out of 6 and she's been there for everyone else but doesn't wanna be there for me. Sorry had to go on a rant😔
