What is wrong with me?

It took us awhile to get pregnant (8 months) and I had a miscarriage along the way. My sister (2 years older) already has 2 little girls (ages 1 and 3). She got pregnant with #3 a month after me - without even thinking about it (as usual). Thrilled for her, but also like, hm, why can't I just get to have the attention for once?

Fast forward a few months...I'm having the first boy in our family and our families were thrilled!! She finds out today she's also having a boy. My reaction? Sad and annoyed that once again she is "stealing thunder." Life is not a competition, I know...but she is a taker, not a giver, and I thought for once it could be exciting for my husband and I to have the "first" something. She's the type that everything I do is never that exciting because she has already done it, etc. Of course, my second reaction: We'll have our sons so close in age, it will be fun.

Also, she has cervical incompetence so will likely give birth before me even though she's due a month later....so she'll probably have the first grandson anyways. Maybe I'll pretend like this is just pregnancy hormones and I'm not a mean person. : (
