My son is now 6 weeks old. and i am still unable to establish breastfeeding. it takes him 10 minutes to latch, and when i think we are successful, he starts screaming and arching his back and thrashing about. when i can actually get him latched he will nurse for over 1 hr straight and then cry some more. i have alternated breasts, i pump religiously every 2 hrs when i am at home and i am only able to pump out a total of less then one oz for both breasts combined, this is inbetween bfing. it takes 3 pumping sessions to get that much milk out. he has not gained any weight his birth weight was 6lbs 1 oz, and he is now weighing 5lbs 5oz.. the our family practice doc is very very concerned, and he is reluctantly telling me to supplement with formula. I am a failure.
