Baby #2 is also going to be born in August! Found out I’m 9 weeks and 5 days!

I paid to have an ultrasound done with a gender blood test (SneakPeek) today because my Dr couldn’t get me an ultrasound until January 20th!! Obviously I wasn’t waiting any longer. Heartbeat is 165

My son is 17 months and his birthday is August 13th.. there’s no way I’ll be able to do a birthday party after the baby so do y’all think it’s okay to do a birthday party 2 weeks or more before so I’m able to attend without a new born?
