Has anyone on here done a super casual “Baby-Que/BabyQ” VS a traditional baby shower?

I LOVE attending and planning baby showers for others, but I’ve never wanted to have one for myself. I never even did a bridal/engagement party and for our wedding, we asked guests to bring their favorite side dish with the recipe instead of registering anywhere.

I’ve had a few people tell me I really need to have a baby shower bc there are lots of people excited for us and want to celebrate. I was trying to find something super causal (like how we did our wedding) and saw the “BabyQ” invites on Pinterest. This is something I think DH and I would really enjoy; we’d have ppl over to celebrate but it wouldn’t be a traditional shower with the games and present opening. The only thing is I’ve had people ask “how will guests know what to get you?” But I don’t really want them to get me anything. I don’t want to register anywhere, just have the party for celebration. The few ppl I’ve told this too though said guests are going to want to bring us something though, and will want to know what that should be.

Has anyone done a “babyQ” like this? Did you still register somewhere, or what did you do if guests asked what to get you? Just looking for tips and trying to decide what to do.
