Am I in the wrong for refusing to continue offering free childcare for my stepdaughter?

Unfortunately, Alice and her boyfriend, Sam, made that almost impossible.

Alice and Sam had always been a bit high-maintenance, but I wasn’t prepared for the three-page list they handed me when Alice was just ten weeks pregnant.

“We’ve put together some rules,” Alice said, her voice overly casual. “If you’re going to babysit my baby, you’ll need to agree to these.”
I skimmed the list, and my jaw nearly hit the floor.

“I can’t cook? I can’t have more than one other grandchild over? And what’s this about my cat? Muffin has to stay out of the baby’s rooms, even when your baby’s not here?” I looked at them incredulously. “This is… a lot.”

Sam folded his arms. “It’s for our baby’s safety.”
“Safety?” My voice rose. “I raised three children, helped raise two stepchildren, and have been caring for four grandchildren without a single incident. What exactly are you implying about my capabilities?”

“Times have changed, Ruby,” Sam said dismissively. “There are new studies, new recommendations —”

“New recommendations about cooking?” I interrupted, my hands trembling with anger. “About having siblings and cousins around? About cats that have been part of the family longer than you have?”
“Mom,” Alice pleaded, “we just want what’s best for our baby.”
