I know I'm still very early in my pregnancy however I promised my younger sister last time I was pregnant she could throw me a gender reveal party. Unfortunately it ended up being a ectopic pregnancy. I promised her she could throw me a party this time around as well. But she is completely clueless on what she wants to do. Lol

She said she might do a bit of a guessing game with the guests but other than that she doesn't know what to do.

Do any of you have any cute/cheap ideas for a gender reveal?

I only say cheap because she is still in College. She is refusing to allow me to help pay for it because she wants to do it on her own.

Side note:

Do any of you have any ideas for a pregnancy announcement that my son can be apart of? I've seen a few with "Big brother" shirts on but I kinda wanted something a little bit different.
