Baby shower or sprinkle??

So ladies, I had my daughter 3 years ago and celebrated with a nice shower! We got tons since SO and I both have larger families. We got rid of a lot of stuff, since we figured we wouldn't have anymore kiddos for awhile. BUT, things didn't go that way, because I'm 21weeks with a BOY!. Should I celebrate with a shower since it's been 3 years and it's a different gender? OR do I have a sprinkle for him?
