I have been pumping after 4month old eats for 2 days and I am not getting anything. I have a medela pump and it works great if I pump when baby hasn't eatten. But b/c baby and I are going to be apart during vacation in a week I needed to ramp up my supply and store some milk. I have been pumping after every feeding AND pumping an hour and a half (for 15-20 min)after baby is done. So basicly my breasts are stimulated every hour and a half. I'm not getting anything!? I didn't expect to get much of anything at first b/c my supply isn't used to it but still after 2 days I'm not getting anymore. I have been eating oatmeal and watching calorie intake(more) and drinking lots of water and getting sleep. But no extra milk. My nipples are purple and I'm tired of waisting my time. Will I eventually get something or is this all in vain. I'm so frustrated b/c I have an expensive pump and it's not working in this regard (I've pump dozens of times-so I know how to use it and know it works) Why won't my supply adjust and increase to all this extra stimulation????
