2. Playing with babies
This has to be the ultimate deal sealer. There is something about men playing with babies that women absolutely adore. They go crazy every time they see a guy who is good with kids. And if the baby happens to be somebody related to the woman and the baby likes you back then you can be assured that the woman is never leaving you. Maybe watching you take so good care of the baby makes the woman realize that you can be sensitive and not hurt them and that you will take care of her too.
