In laws being petty…children involved

Long story short, I’m a mom of 2–a 3yo boy and a 1yo girl. I’ve had a great relationship with my in laws until last year. They would help us a lot with my son. Recently we’ve become a family of 4—which as you know, is EXHAUSTING. And we’ve been doing it all on our own.

Last year my MIL overstepped boundaries with my parenting/discipline and I set boundaries about letting me do the discipline with my kids. She shut down and didn’t talk to me for 2 months. She completely withdrew from me, didn’t talk to me if my husband wasn’t around and doesn’t help with the kids at all. My daughter is 1 and she’s never offered to babysit.

Fast forward to now, my husband and I have reached out repeatedly for help in the last few months only to be dismissed over and over again. Excuse after excuse. It’s just sad. They begged us to have kids and then we had a surprise second. We are drowning and I’ve been in and out of depression. I’ve become the black sheep in this family for just setting boundaries.

I’m all alone in this and no friends around for me to lean on because I’ve been fully sucked into motherhood being the primary caregiver 24/7. I’m so tired and I needed the rant/advice from others who have experienced something like this.

Are they being petty or is it just all in my head?
