Mothers Law

Mother's Law; noun
The Mother version of Murphy's Law.

As originally defined in Mikayla's Dictionary published 2024;
When a mom's time and motivation align perfectly to complete tasks otherwise usually pushed aside for lack of time or motivation alignment, the Mother's children will then undoubtedly become extraordinarily clingy, perform dangerous acts and hurt themselves requiring comfort and consoling, fight with siblings (both verbally and physically) and cause various alternative chaotic acts within the home environment, therefore causing the tasks or projects to yet again go undone or possibly worsen.

I finally had the time and willpower to (insert task here) but then the kids went feral - that's Mothers Law for you!
