Am I overreacting?

Okay this is my first post but i really need advice along with alternative opinions that could maybe help me deal with my situation better…? So to start off I am F19, my bf is M21 & we live with his parents. I have been living with them for some time due to a strained relationship with my dad. since after i graduated high school in june of 2023. We found out I was pregnant Feb of 2024. Shortly after we told my bf’s parents & ofc they were excited.

As time went on I did start to get closer with my mil and i was coming out of my shell & having conversations with her a lot. Sometimes when we would talk she would bring up about how she couldn’t have babies anymore. I think it was only 2 or 3 instances where she brought it up. First time was her saying how she regrets tying her tubes so young. (She had a boy(my bf) & girl back to back, so ig she was content & happy at the time). Second comment was about how she wanted to get prego soo bad after realizing she regretted tying her tubes. She would miss her period and thought she felt kicks in her stomach. Which ik is a normal experience (especially after pp). But she had her tubes tied & would still think this way multiple times & like more than 10 years later. Like to me that kind of shows how desperate she wanted a baby. At first I didn’t think anything of these comments. But the behaviors she exhibits now, makes me look back at these comments and wonder if she thought she was going to be finally getting her baby she always wanted? Bc why else make those comments while i’m pregnant? Like im not having her for you… for ANYBODY.

Another time was the first time we brought LO to a restaurant. I had to change her diaper so her & sil came to also use rr & help me. Which was fine with me i carried LO to rr, changed her, then mil asked if i wanted her to hold baby while i washed my hands. I said yes, & as i was almost done about to dry my hands mil walks out with LO along with SIL & that made me sad walking out the rr without my LO following along while my MIl is walking way ahead. In that moment i just felt so empty, ik it might sound dramatic but i watched as she carried her across the restaurant like it was her baby. I just feel like she should’ve waited for me at least?? Or ask simply “Can i take her back to the table?” Instead of feeling so entitled you just take her from me. At this time I had NO backbone and didn’t say anything. Even an incident at church, we were in the nursery & while i was playing with my baby, I turn & my mil has a balloon in her shirt & she’s saying “Im pregnant , Im pregnant!, it’s a girl!”. I just couldn’t help but chuckle, & mind you my LO is a girl. These are just the worst of the worst she’s done but when baby is not involved we get along. It’s so hard to be mad bc she does help me with her while I shower or eat, and spoils LO so much but I can’t help but feel like she wants a second chance with my baby & that makes me not want any help from her at all.

My baby also watches Ms.Rachel for a short time period of the day while i get things done. & one of the things she says is “Can you say mama, mama, can you say mamas name” & she ALWAYS is repeating this to her. & it’s mostly when im not around. We also live with another LO who is my bf’s cousins baby but she does not exhibit this behavior with that mother or her LO. Am I overreacting?
