AITA for telling my husband that his mother is overstepping and I don’t want her in the delivery room?

I (32F) am currently 8 months pregnant with our first child. My husband, Tom (35M), and I have been together for seven years, and overall, we have a great relationship. The only issue? His mom (62F), Linda.

Linda has always been overbearing—the type of mother who still calls her son “my baby” and insists she knows what’s best for him. Since we announced the pregnancy, she’s been way too involved. She constantly gives unsolicited advice, criticizes my choices, and even refers to the baby as “our baby”, which makes me uncomfortable.

The breaking point came last week when she casually said, “I can’t wait to be there for the birth! I want to be the first to hold my grandbaby.” I was shocked. I never invited her, and I had always assumed the only person with me (besides the medical staff) would be my husband.

I told her, as politely as possible, that I wasn’t comfortable having anyone except Tom in the delivery room. She immediately flipped out, saying it was unfair, that she had “a right” to be there, and that she was present for the births of her nieces and nephews. She even accused me of trying to “push her out of the baby’s life.”

Later, Tom told me I should “just let her be there” to keep the peace, since it’s a big moment for the family. I told him this is MY medical procedure, and I should have control over who is in the room. He said I was being dramatic and that “it’s just a few extra people.”

Now, I feel like I’m being ganged up on. I don’t want to destroy my relationship with my MIL, but I also don’t want to feel uncomfortable during such an important moment.

AITA?
