I have a 41 days old baby. I have flat/inverted nipples. I have tried nipple shield for feeding but my baby is struggling with to drink with shield. So , I have decided to pump exclusively and feed her through bottle. I have bought single electric pump and started pumping. Everytime I pump, I get 1 drop per suction or 1 drop per 2 to 3 suctions. With this, it's taking almost an hour to pump about 70 ml from both breasts per session. I want to know if this is how it is supposed to be or am I doing something wrong.
