I Really Wish We Could Celebrate Without It Being Tacky

So I'm pregnant with my second boy. My son is 3 so I still have most everything from him. We lived in a different state when he was born. He was born in the winter, and this baby will be born at the beginning of the summer. I've already purchased anything new I needed for the nursery. 
My mom and a friend of hers is hosting a baby sprinkle for me in another state. It's isn't about gifts, but celebrating a little life that at one point I wasn't sure would make it. The hostess asked me to register. So I did...diapers, wipes, baby bath stuff, binkies. You know, stuff you need with each kiddo. Maybe a few summer clothes since my first boy was born in the winter. Her friends have expressed wanting to get us gift cards so we can buy as we need along and along. I'm truly thrilled at their offer to host. It's really kind. 
The truth is I don't even know the hostess. This is my mom's party with her friends from her church, 12 hours from where I live. I'm honored these ladies wanna celebrate. I'm honrored they're so excited. I'm just excited that people are excited. And it will be super low key. Some close friends of my mothers. And my child's godmother. 
But secretly, I'd love a little bash here with some ladies from the church and a few friends. Granted, I don't have a lot of young moms here, but I do go to a small church. And I'd love to have some kind of cake and punch celebration of this new little life. Maybe something that said no gifts please? 
I was asked if I was having a shower locally. I said I hadn't heard any plans. I feel like it's tacky for me to personally throw a shower for myself for a child of the same gender that is only 3 years apart from my first. I had a friend that was interested in throwing me one until she found out it was another boy. Totally understand. I really don't need much of anything. 
But our people seem to think any celebrating is tacky because I'm having another boy especially for me to host myself. I really don't want gifts, but a cake, some snacks, and just some fun with friends? I guess everyone feels like even when you say no gifts, they still feel like they need to. I know. I'm going to a wedding this weekend that said no gifts, and I got a little something for the bride. It's just what Southerneres do. 
Is it wrong to have a little celebration, no gifts expected? Or is it totally tacky?
