There are many factors when it comes to breast feeding, its not just an inability on the mothers side to think of ie lack of milk, lack of feeding education or confidance about it.
There is another person involved as well and sometimes that little person just plain refuses to play along.
Brian hated bf, he clawed at me, pulled away pushed me away, screamed, cried he has hated being held that way since day one even now I cant get him to lay down in my arms unless hes about to drop off and I lay him back after hes asleep.
He just hates feeling restricted.
I even tried bf laying on the bed so I wasnt holding him against me but he wasnt having any of it he would just thrash his head around away from me so violantly I was worried hed hurt himself.
It would take me about an hour to get him to latch on and that would only last about 4-5 minutes even the hv said he was just refusing to latch on (imagine how thinking your baby doesnt want to be near you feels)
Soon as I tried a bottle it was completly differant, he was calm, happy and feeding well.
I did try expressing but without the natural sucking I just couldnt produce with just expressing alone plus I had a lousy pump that leaked more then it gathered.
So while breast may be nutritionaly best its not always emotionaly, physicaly, mentaly best
