I got pregnant when I was 16. I had currently been with my boyfriend for about 2 years. Well my parents were convinced that he would not stick around, and basically gave me no choice but to give our son MY last name. Well our son is now 2 and we are 18 and 19. We have now been together for 4 1/2 years, are living together, and plan to get married in the future. My question is, How can we go about changing our son's last name to my boyfriends? He is the father on the birth certificate and everything, and its what we both want...we just aren't sure how to do it...(we are in Florida)
