First time mom emotions

Hey ladies, so I’m a first time mom and just reached second trimester. We’ve told our families, baby is healthy, everything is great

BUT

My husbands mom kind of upsets me. She’s had two boys of her own (my husband being the oldest) and his brother who is still a minor living in the house. Well ever since announcing, she’s called our baby “mine” and refers to the baby as a girl cause that’s what she wants. I’m all for having a girl but it’s the “my baby” “I’m finding out what I’m having soon” is what’s bothersome.

We live in a different state and she automatically said we’re having the baby shower in his home state, meaning we have to travel, and said to his family members “they don’t want to have a baby shower here but we’re doing it in March” and “she’ll (meaning me) be able to travel cause she won’t be sick anymore”, it’s amazing she wants to do it but i get car sick, I’ve had a rough pregnancy, we’re having a baby shower in our state we live in where my family is traveling to us and she didn’t even consider coming to us cause she “hates the town we live in”. I’ve told my husband he needs to handle it cause I’m all new to this and feel like my pregnancy is being taken from me. Not to mention his family members telling me how huge I am and it MUST be twins over and over even though we have pictures of one baby.

I’m sorry for the rant, I’m emotional and trying to share this with family cause it’s a great time (first grand baby on both sides of the family) but I just feel awful about it all sometimes, like I’m just the incubator for everyone else’s “baby”.

Any advice would be appreciated!
