I can spot a fake
Coach a mile away. I would be traumatized to have to carry a fake one and definitely feel for you. The problem with telling her it was either ruined through soiling of grape juice or being ripped off is this a) she thinks you like knockoffs or that she fooled you with the knock off and will continue buy them for you. b) she feels bad your diaper bag got lost/stolen/damaged and she will replace it for you at your next gift exchange. Maybe the best is to tell her the handle came unglued and fell off while carrying and that you were completely humiliated. She will hopefully then realize knockoffs are complete garbage and won't consider giving them to anyone. I would even rip the handle off and show her LOL!
