I’m asking advice about whether to interfere with the way my grandchildren, ages 9 and 7, are being parented. The rationale from my DIL was that they wanted to take away something that was meaningful. She found some paint on an upholstered dining chair and went into an all-out rage at my granddaughter. My hope is that what you see is only part of the childrearing conversations between your son and his wife. However, that doesn’t necessarily mean you can’t discretely remind your son of how difficult it can be to live with someone with a dangerously short fuse, since you’ve been there, done that.
