call me crazy

Brittney
Long story short, my younger sister and I found it we were pregnant around the same time. Since day one, she has been very rude about me being pregnant. She makes little comments like, "your baby is going to steal my thunder" type comments. She is mad that we share this experience. I get it's her first child, but come on. There is plenty of love to go around to both babies. But the way she is acting has made it very difficult to even be around her. We found out through blood tests that we are having a little girl. She is doing her gender reveal party this weekend!! I pray for her everyday, that she has a healthy baby and that's all that matter. But am I a terrible person If I hope she doesn't have a girl. Does this make me sound like her? I just have a feeling her attitude will only get worse if we end up having the same gender. Please, tell me I'm crazy!!
