If my baby girl is fed will her odds of being increase? how do i make it stop?

my wife and i just had a girl. our first was a boy. he is now 3 yrs old and he was fed. i had no problem with the brestfeeding. now with the baby girl i figured she would be fed too i had no problems with that until i saw her being fed. its been about 2 weeks and i cant get rid of this feeling that shes going to turn out to be . she really attacks my wifes moreso than my boy when he was a baby. it just doest seem right and i cant help but wonder if this is how s are made? i fear she will be if she isnt bottle fed. does anyone have any advice or experience here? is this an act of ism? should i stay pissed at my wife for what shes doing to my child? the arguing is getting intense. i hate the idea of someones **** bieng forced in my baby girls face.
