I had a baby three weeks ago, my first. MIL (who is staying for a week) has just shrieked ' My goodness girl, haven't you got an appetite! You better not weigh yourself for a while!' because I ate the last slice of banana loaf.
I want to tell her to fuck off, but realise I'm probably being touchy because I'm tired.
Do I need to just let it go, and if yes, then can someone please tell me how to?
