Family Drama About Baby Names

I just had my son the beginning of January and my sister in law is due with her 3rd child in March, so soon! We just found out that she’s having a boy after having a boy and girl already. We chose an amazing name for our son and was so excited to find a great name, and like we’ve done before with our other babies, we didn’t share until right before birth. Turns out my SIL also chose the same name if having a boy, and after my son was born, she is still going through with using the same name. I’m honestly shocked! I would’ve thought it would have been common courtesy to choose a different name so that all the first cousins had their own names. If I was in the position of a niece/nephew being born before my own child with the name I wanted, I would’ve gone with a different name even though I’d be disappointed. I personally find it so weird for first cousins to have the same name, especially when born so close together.

I want to reach out and ask if she would consider choosing a different name or maybe just shift the name to be the middle name. But should I even reach out? Is that too much to ask? Am I being overly dramatic over this? It honestly hurt my feelings to hear that she is still going for the same name after we went through so much stuff with this pregnancy and birth for our son to be here (I lost my daughter after I found I was pregnant with him, then he wasn’t growing well and I had pre-eclampsia). I’ve never had an issues with my SIL but now this brings up problems for me. I didn’t think I had to ever clarify with family about this, and my husband is shocked too since his parents are encouraging it. I feel so lost about all of this 😭
