Wita for telling mil she can’t come when I have to give birth

S

I live states away from family. I want my mom to come for baby #2’s birth but if she can’t, I want my twin here so she can stay with my toddler. It made me so annoyed that my mil assumed she would be the one here to watch her when I have family. We get along fine but I don’t want her here for a week or two after baby is born. I don’t want a full house and I only want people I love and trust, my mom and my twin. I didn’t correct her when she said she’d be coming since I know she was just excited from us announcing the pregnancy. But I will definitely be telling her she’s not the one that’s gonna be here to watch my toddler.
