Baby shower or sip and see?

Hello gorgeous glow Momma's! I'm in need of advice/opinions. My husband and I are being blessed with a surprise baby! This is our third child and we are keeping the gender a surprise until delivery! (It's been so hard not to change my mind!) We have a beautiful 6 year old girl and a handsome 22 month old boy. With us being blessed with one of each we thought it would be so fun and exciting to let this little blessing of joy be a surprise. It is very exciting but also makes preparing for this baby a little difficult. I didn't keep most of the clothes from my daughter once I found out my 2nd was a boy. I do have a lot of his clothes saved back though. That brings me to my question, with this being my third child would having a shower come off as seeming greedy? Should we have a shower and ask for gender neutral clothing and/or the essentials (bottles,wipes, diapers, etc)? Or would a post baby gathering aka a sip and see be the better option? I don't want anyone to feel like we're being greedy or feel obligated to give us anything other than their love. I also know that this baby will need clothes to wear and some people have seemed irritated that I currently don't plan on having a shower. Help me out! Your ideas and advice are always much appreciated! Thank you!
