I breastfeed and supplement if I have to after. My baby will usually take 3 oz of just the formula at 2 weeks and a half and when I breastfeed he seems full and falls asleep for the 3-4 hours in between of feedings. Now my question is, if my baby is full when I breastfeed him, why can’t I get enough milk out when I pump? I’m only able to get about an oz (at most) out of both breasts combined. I have the lansinoh 2.0 smart pump and have also tried the medela and evenflo hand pump. Still, I get the same amount out. How can I increase my supply or is there another pump anyone can recommend?
