Either way is great however you want to do it it's for u. My aunt is throwing me a fam one but im throwing my own for friends and coworkers cuz i know they honestly wouldn't take the time and effort to plan it for me
I wouldn't think it matters some people don't even have baby showers its not in the handbook that you have to have a baby shower or someone else has to set the baby shower for you lol :)
You can have your own :) doesn't have to be someone else organising it :)
