18-year-old asked to babysit her 25 and 28-year-old stepsister's children during 3-day vacation: 'There was a lot of back and forth on this'

These step-siblings aren't just disagreeing — 2 of the 3 women are acting totally unfairly towards their stepsister. 

When your siblings have kids and you get to become an aunt or uncle, it's a joy for many families. You suddenly get to hang out with not only your favorite brother or sister, but also their tiny mini-me! You get to play with a cute little baby, taking them to playgrounds or the library, giving your sibling a break from the exhaustion of parenting. The best part is that you get to experience the joys of hanging out with your niece or nephew, and then give them back to your sibling at the end of the day and head home alone. Having a child is quite a big responsibility, and it takes a village. But some parents get so used to their sibling (or step-sibling) taking on responsibilities that they start to take advantage of their niceness. Keep that in mind as you read about these stepsisters were absolutely awful to their stepsister, which you can read all about below.
