Overbearing Family Members

How do you deal with overbearing parents or other family members during this wonderful, yet stressful as hell life event? Historically, my mother and I have always had a strained relationship (hello, toxic parenting!). I struggled with sharing the news of my pregnancy with her for a long while, but felt it was the "right" thing to do. I should've trusted my gut as she's been crazy ever since 😩 As a private person, I have not told anyone else our news, outside of close family - I'm waiting until the twelve-week ultrasound to confirm the baby's in good health before I tell any others. What does Mom do? Consistently calls and texts with questions about my health, already suggesting baby names and what the child will call her, asking if I'll be using cloth diapers, when she can start cruising yard sales for deals on baby furniture and on and on. In theory, this sounds great and supportive, but it is one of her manipulative ways to insert herself into my adult life yet again - a place where I (and my significant other) do not want her to be. I've asked her repeatedly to respect my privacy and to give me space, to no avail. How should I even handle this?
