Mommas due on 12/21/15

I am 19 weeks and today I will be going in to do my 60min ultrasound  appointment and also find out gender (hopefully lol)  🎀💙 I am excited that we choose to find out gender this time :) my son who is 4 we had the gender picture sealed in an envelope and opened it after he was born. Although that was a lot of fun to wait, I want to experience both. 
So here it goes... What is your gender guess for baby 🎀 or 💙?? Oh, heart rate at 17 weeks was 153.
Also if you know the gender and you are due on 12/21/15 what are you having?
