I hate the fact that when we did the birth certificate at the hospital we put the babys last name as Perez (babydaddys moms last name) when my babydaddys last name is awkwardly the same as mine, Lopez. (no we arent related😂) The nurse looked at me like uhhh are you the birth dad? Hes in the middle of a last name change because he doesnt want his dads last name anymore he wants his moms which is Perez so we made the babys last name Perez since his will be changed soon. It better be fully changed by time the new baby comes I am not gonna look stupid doing the birth certificate again with Perez and hes still Lopez😡
