Maybe my daughters are angels compared to the rest of your kids, but my youngest tried this once and both learned “If daddy says get off the laptop, that means NOW. because spankings hurt and laptops are a privilege” and I didn’t even have to make it a rule, its now just considered general knowledge.
I am the Meanest Mommy in the Whole Wide World. I am forced to make rules & observations that I never knew would be necessary before I became a parent.
