Breastfeeding mommies : I usually pump and feed my son because he wouldn't latch and two weeks ago I got him to latch and now everyday im pumping and breastfeeding in between and my breast/nipples hurt badly from doing both.& I realized I wasn't producing enough milk ,he used to eat 4oz now it's down to 2oz from both left & right breast so.i turned to similac I started yesterday and i notice he wasn't having bms as usual and being fussy and straining so today I bought similac sencitive tummy for fussiness and gas. Do u think I should put one scoop of each ? I need help/advice my son will be 1MONTH this week.
