Thanks yall! I've thought about the booties and onesie idea but didn't really know how to go about it :)
I had the ultrasound tech put a little pink or blue sock in a box and we opened it all together. You could each blow up a blue and pink balloon and pop whichever it isn't. I think you should have your doctor put the gender in an envelope or something and open it with your husband, then do a fun announcement picture on Facebook. Pinterest has a toooon of cute ideas!
Buy some little pink or blue booties and have someone (or take a picture in the mirror) and hold the booties or onesie on your belly and him holding you from the back. Or a pink or blue balloon and blow it up but don't tie it yet and write it's a girl or boy or a cute message and take a selfie lol looking at your husband. I did the ballon one
Sumthin along the lines of saying roses are red n violets are blue. ..lol
