Gender reveal advice

lo
I want to do it SO BAD but my family sucks. They're not excited that I'm pregnant since I'm 18 & the baby father or his family isn't there for me. Would it be weird if I did it to just my mom & siblings? I was thinking about making pink or blue cake pops so when they bite into it they'll find out what it is. I'm finally happy with my pregnancy & my mom is adapting. If you think this would suck suggest something different or if you have a better idea let me know please!
