I'm on maternity leave and have been pumping once a day with my medela freestyle. The past week or so the suction on my right side seems way less than my left. The flange looked a little big on that side so I switched to the smaller one on the right but am still using the bigger one on the left. I thought it was helping but now I'm having the same problem again. The right nipple is hardly even getting drawn into the flange! I have to keep turning the suction up to get anything from the right but now i think the left nipple is getting damaged from the extra suction on that side . All of the parts look ok (the freestyle doesn't have tiny little membranes like the other medela pumps) and it doesn't help to switch the parts on the two sides. Am I missing something here?
