Dad coming to doctor appointments

Saphonia

So even though this is my third pregnancy, in my first relationship my children's father was not very hands on during my pregnancy or with much of any parts of the relationship. So this time around it's pretty great that my current boyfriend wants to be apart of everything he recently came to an appointment with me for the first time my 20 week US which was on his birthday. He was very into it and asking questions. It made me super happy. Now he is planing to come to the remaining appointments with me. I don't know if it's because I'm just not use to this or if it is a normal thing that dads do. Was this strange for anyone else. Or am I just weird because it's never happen to me.
