Very interesting. Opens up a lot of questions.
I knew a girl here that didn't want her bf to have anything to do with her baby, since they had broken up before she knew she was pregnant. When her daughter was born, she told the doctor that it was a one night stand and she had no clue as to the name of the guy that was the father (since she had to complete a birth certificate). Not saying what she did was right or wrong - just that's how that went down.
Wonder if our adoption laws require father knowing???
I also knew a guy that had a one night stand and 17 years later discovered he had a daughter with this woman (he demanded a paternity test once he found out). He had a son with his wife that was only a few months younger than this unknown daughter, and the two children went to school together and knew one another. Can you imagine if they had dated? You'd think this stuff only happens on general hospital.
