DD is 18 weeks old and have been mixed feeding her successfully for 4 weeks. Formula twice a day and expressing the rest of the time, 3-4 times a day, using a Medela Swing pump. The pump worked brilliantly and I was getting off 100-150ml each side.
Problem is yesterday I started pumping as usual but only got around 50ml total (ie both sides). Tried again a few hours later and got 20ml. It seems to me that the pump isn't working as well, it isn't 'sucking' the nipple as powerfully even when it is on maximum, although it still sounds the same (loud). Has anyone else had the same experience? Pump is connected to mains so not a battery issue.
To start with I was worried my supplied had suddenly dried up but now am convinced it's in there are they are now hard in places. Have tried hand expressing but not sure of how to do it properly.
Grateful for any advice!
