To give you a bit of a background, my MIL is usually a generous, warm and amazing person, super supportive. We do come however from very different backgrounds- she from a multi kids family, she has had 8 siblings herself, everyone married young, and if not match maker would be involved, etc, which crates frictions.
She has been nagging me and my partner for a grandchild for a long time, which I found very intrusive. I am personally super annoyed when people interfere with such an intimate sphere of my life, and always believed it should be between me and my partner, not our families. We did want children, but the 'subtle' "you know, you are not getting any younger" was really getting to me. My partner's sibling is nowhere near having children, neither of the two being in a relationship, so she pinned all her hopes on us, but I kind of never told her to pipe down with her comments as I respect her for a lot of other things.
Long story short, I gave birth a few months ago. MIL is in love, as we all are, as it is her first grandson and all. She does seem however to think, and lets me know, that she disapproves of our parenting, and seems like she thinks we are, in facts, idiots, and that she loves and cares for our baby more than us. She also tends to wind herself up about us possibly making a decision wrong for the baby, which we would not even consider, and then rings us to make sure we will not do it (f.ex. when he was in incubator after being born, she kept on ringing my partner to make sure we would not kidnap him from NICU (!!!) and that we would let the doctors treat him- like if we planned to stop them doing their jobs!).
The other day I mentioned we were looking into a particular treatment for him because of his reflux and she said something along the lines that she would never let us hurt the baby, although she never heard of the treatment and did not even know what it was. She then went on to say she would ask her friends about the treatment as she relies heavily on what her friends say (it's a thing she does, everything in her world is recommended by such friend or another), but disregards mine and my partner's research that we spent a lot of time on.
I think it just hurt me the most that she thinks WE would want to hurt our son by making stupid/rash decisions, and that she thinks she needs to hang around to protect him.
I actually think she sees him as almost her own son- she even told me she would be happy to take the baby away to her house and bring him up on her own if we struggle (no one asked her- we are coping fine with the baby despite having understandably some very difficult moments). I don't know if I should speak to her about it, and how to do it without hurting her feeling. Unfortunately for myself I am a person who looses sleep over things like this and I want to let her know that I am not happy with being treated like an incompetent parent. Plus she wants more than one grandchild, so she already started hinting we need to start working on another!
