annoyed 😒

So I am pregnant with my first baby. My sister asked me if she could plan my baby shower, so I said yes. I had decided that I would like to have an adult only baby shower, and she flipped a lid and told me it was best if I got someone else to plan the shower.? Never once did she ask me how I in visioned my shower. The reason why I wanted to have an adult only shower isn't because I hate kids. I love kids, this is why I'm having one of my own. I wanted an adult party only because we're not doing it at my home, I live 2.5 hours away from everyone and made the choice to have it where everyone is to make it easier for everyone. We're renting out a club house of a townhouse complex we used to live in. So there's nothing there to really keep the kids entertained. There are 20 people coming and out of those 20 people there would be 10 kids which are all 10 and under. I just wanted parents to be able to get away and have a few hours of just them time to enjoy the shower. Anyways I told all my friends who had children before the invites go out that it will be adult only and all of them said no worries, whatever works for you works for me. It's just my sister who has an issue with it and now told me to get someone else to plan it. When did it become okay to completely make someone feel like shit for wanting their baby shower a certain way. I understand that not everyone could get a sitter and I wouldn't have been hurt if someone couldn't come because of it. If this was happening at my home, it would be completely different because we have the means to entertain kids. We have a games/play room and could have defiantly accommodated. Just sad that my own sister did this.
