Breast feeding

Daesha

So my first born .my Daughter I tried to breastfeed her she didn’t take it but I was young and her father told me no I shouldn’t do it

So now I’m pregnant by a different guy and I wanna breastfeed w my 2nd or at least see if the baby takes it the father doesn’t want me to breastfeed niether

Should I jus try to breastfeed like I want to do and see wha happen?
