Maybe address it in person. I know it’s super awkward, but a text can be read in a tone it wasn’t meant to come off as. I think what you are saying is fine, just do it face to face.

I don’t think so you’re straight and to the point

Sometimes you have to be “harsh” with your MIL. I think it’s straightforward especially if y’all have had to address it before

Yes, sounds like she’s trying to be helpful even if it’s overbearing. If it’s the first time this has happened, try a little more tact or have your husband address it.

I agree with doing it in person also so you can be stern about YOUR parenting decisions and rules that you wish for her to respect. I have the same probs with my MIL , and I have been with my boyfriend for 7 years. We are having our 3rd kid and she still takes my parenting as a joke and steps on my feet at times. And I always had to let her know that I will always be the mother of my kids like it/me or not. That’s fine, but her say about stuff or feelings is not too much my priority for my kids life.

Another vote for handling this in person if at all possible.

Too harsh? Girl you should see the text I finally sent my mil. It was MONTHS in the making and she finally made me snap

Your ending of thank you sounds very abrupt, which changes the tone to being pissed off. I’d recommend talking to her in person and telling her that you understand she’s trying to help out, but when you’re present you’d prefer if she wait until she’s asked before stepping in
