telling your dad

I found out yesterday that my second child will be another baby boy, all of my family knows but my grandmother and my dad. Me and my dad don't have a perfect relationship and I would like to tell him but I'm not sure how. When I had my first son I was 17 and was still at home of course and everyone was very upset when they found out. But this time I have a good job and so does the boyfriend and we live on our own and we want to be excited I just need help telling my dad 😊
