Am I selfish?

Bri • Army national guard• mommy of 1

I am 14 weeks pregnant & I've always been very independent. But I've been thinking about my birth & honestly I would like to have just me & my s/o there for a while. I don't want my family nor do i want his there & I wanna get to spend some alone time with just the three of us before everyone starts playing hot potato with my baby. I don't wanna be rude I'd just rather us have a more privacy i guess since we haven't been getting alot of it since the pregnancy especially when it comes to his mother. His father is fine but his mother is just so overbearing i guess & i can only deal with so much of her at once. Im also in the process of thinking of baby names with my s/o & she chimes in & kept suggesting that we name the baby after her & im just getting really frustrated with her. Shes nice & means well but she's just too much. She was even explaining something about breastfeeding & then proceeded to show me her breast (mind you she is over 45 & has had 5 kids 😓) I just want a bit more privacy in my life with just me, my s/o & baby. I just know if she comes to the hospital she's gonna wanna hold the baby all the time & start coaching me on what i need to do now to rais my child & all that other stuff i dont wanna hear. I just wanna be alone with my s/o & baby. Im also 19 & so she lectures me & tries to basically "mom" me & tell me what i need to do for the baby & i feel like its because im young everyone treats me like i dont know what im doing. Is that a bad thing that i feel this way? Am i just being a bitch or what?
