Meet a 27-year-old foster mom facing a family rift that goes beyond sibling squabbles. It all started when her older sister, Kate, moved in temporarily after experiencing a heartbreaking miscarriage and filing for divorce. While Kate is a supportive sister to the foster mom, her behavior towards May, the 5-year-old foster daughter, is far from kind.

May tries to connect with her aunt, only to be met with snaps and tears. The foster mom understands that grief has taken its toll on Kate, but she’s not willing to accept her sister mistreating a young child as a justified consequence. Despite multiple attempts to address the issue, Kate remains resistant to change.

The breaking point comes when May innocently asks Kate to move aside in the morning, triggering a dismissive response. Unable to tolerate the mistreatment any longer, the foster mom steps in, demanding an apology and revealing the heart-wrenching reason behind Kate’s behavior. Get ready for a tale of family dynamics, compassion, and the unexpected twists that unfold in the midst of difficult circumstances.

1. Staying at your sister’s house and not being able to stand her daughter…what else did she expect?

2. OP is planning to adopt her foster daughter, May, after spending the best 8 months of her life with her.

3. OP’s sister, Kate, since filing for divorce after her miscarriage has been living with her.

4. The relationship between Kate and May, though, has been terrible since inception and the problem is with the way Kate reacts to anything May says or asks.

5. OP has told Kate to stop behaving rudely to May but she doesn’t understand.

6. Even the simplest of requests would be met with aggression and yelling.

7. Kate’s rationale for the rudeness was that May reminded her of a potential future with a baby which will never exist because of the miscarriage she had.

Was May responsible for Kate’s miscarriage? Nope. Perhaps OP did something…absolutely not. Then why in the world is Kate being so rude to May? It isn’t the little girl’s fault she reminds Kate of her miscarriage. This is not the way to deal with your problems or past. Poor May doesn’t even understand all dynamics of world yet and is constantly being met with yelling. And it is Kate who starts crying after doing it. It is like she feels bad but has no control over her emotions when she sees May. Yes, you may feel for her but this is no way to go about it. Kate has to change.
