7 years, 11 months.
I’ve recently discovered that when Mommy and I aren’t closely paying attention, like while we are doing the dishes, you discreetly teach your sister “bad words”, as if it’s your obligation as her older brother.
“Holly… butt cheek.”
She will then repeat it and confirm she knows it’s a new word she shouldn’t say:
Then she grins with gratitude.
However, she doesn’t quite understand the context of most of the Disney-approved bad words you have been teaching her.
That’s why it’s not out of the ordinary for her to casually say, “I want a cheese stick… butt cheek.”
I’m sure in time, though, you’ll be able to teach her how to say these inappropriate phrases a little more appropriately.
