This is honestly what's going on with young mothers these days. They want to grow up to fast, weren't taught to respect elders nor themselves! If she can got into a fit of rage like that its best you get a restraining order, file a report and keep her from your grandson. It only takes once for that baby to be under a TV or behind her and running down the road while she's having a mood swing. ... I'm just being honest! I hope you had witnesses! But seriously those young mothers these days are still kids themselves inside
