Baby’s first birthday

So I decided to post here after a little dispute with my husband over the planning of my daughters first birthday. Actually, let’s backtrack a bit. I’ve started planning my daughters birthday about a month ago (it’s coming up in July) I told his niece (who is about the same age as me) the theme that I’m doing. We’re doing a whimsical theme with fairies and unicorns. I mentioned matching with my daughter and being a fairy (and the kids will be fairies too) Now his niece has decided to dress up as a fairy as well. I already knew that she wanted to dress up so I’m totally cool with it. However, she is now telling me that she is getting her outfit CUSTOM MADE and wants to go ALL out on her outfit. I LOVE her dearly but to be transparent, she does enjoy being in the spotlight ALWAYS. Like I said, I do love her and she helps me a lot with my daughter. They also both look exactly alike. So sometimes I’m a little jelly because I know this and secretly want someone to tell me that my daughter looks like me 😭 (I know it’s silly-but I blame motherhood) Anyway, Iam annoyed because wth...Iam her mother and this is MY daughters first birthday. So like, Can I live?! Now I have to spend so much $ on a customized extravagant fairy wings cuz that’s what she’s doing? Naw fam. I planned on creating it myself. I’m spending so much on decor I’m not sure if I can even afford that...but now I feel like I’ve been put in a position where I have too. Like I said it’s my daughters 1st BIRTHDay. So yes it’s a big deal to me and I want to share that unique moment with my LO...and only my LO! What are your thoughts? I feel so silly to even be thinking about this cuz like who cares really? 😭 But I just can’t help but be annoyed...
