For example, this afternoon she changed our newborn's diaper. My wife looks over and notices she's wiping our baby's butt with clorox wipes. Yes, clorox wipes. She didn't notice they weren't baby wipes and had used 3 wipes until my wife noticed and shrieked. Our baby is 6 days old.
This is why we ask her not to change diapers, but she does it when we're not looking. A couple hours later, she changed the baby's diaper right before bed and somehow got poop all over the baby's hands and pajamas.
Good job, good effort Grandma. Please... just leave it to us though.
