Announcing gender to SO

Originally we planned to wait for the doctor to tell us. Then I found out that I can track my NIPT online and results are posted there. We decided that he wants to hear it from me because it’ll be more personal. I have come up with a present I want to make him but I need y’all a help. I want to make this picture frame with scrapbook letters and for a girl I’m going to put “daddy’s princess” but I have no clue what to call the baby if it’s a boy. Daddy’s what? Then the plan was to put an ultrasound picture in the frame, since we had a few miscarriages before I keep the ultrasound pictures in my wallet and look at them Atleast 3 times a day and I’m not ready to part with them. I’m announcing to him Saturday or Sunday. Our results should be in Friday. But our next appointment isn’t till the 19th and I only have 2 ultrasounds since each ultrasound only gave us one picture. So what should I put for boy and any ideas about the picture would be helpful too!
