This is a phrase my MIL uses a lot when DD isn't acting nice. We see her often so the girls hear this phrase almost daily. Lately, DD1 (3.5) has been telling me "Nana just says I'm ugly". I've tried to explain it to her by telling her she isn't ugly, it means she just was acting very nice, Nana thinks she's beautiful, etc. but it keeps coming up and it's really bothering me. The other day MIL told DD that she was cute and when DD said "no im not" MIL (teasingly, but still) said "okay then you're ugly" and DD dejectedly said "yeah". It's breaking my heart. I know MIL doesn't mean it that way but DD clearly isn't understanding. I want to say something but I don't really know how to broach the topic. WWYD?
