people say my oldest son looks like he's my sisters kid all the time, and you know what? HE'S NOT!! kids don't think like that, first of all, and just because you can BIRTH a baby does not mean you can call it yours, it wouldn't be yours, it would be her child to raise. and you should look at the child like you helped make a miracle, and you done it because you have love for your sister.......do you think that she would do it for you? i don't know you, and i think that if she could, she would. you are being selfish......help your sister out.
