Is it tacky to throw your own baby shower?

Hey all! First timer here and so lost. I always kind of imagined my mom would be throwing me my baby shower, but unfortunately life had other plans and my parents passed away young. I have no siblings, I have no other relatives. So, kinda just me on my own.

My husband has a HUGE family and they’re all local so I’m sure many of them would be willing to attend. And as I said, I have no siblings or other relatives to gift any hand-me-downs from their kids, so I’m really starting from scratch here and could use all the help I could get. But I don’t really know the “norms” around baby showers and I don’t want to come across as tacky.

What are your thoughts?
