FL, as your DD gets a bit older she will most likely sleep less and you will have more time to fit feeds in! Don't forget that supply = demand when BF, so offer the breast as often as you can manage. I took Motilium from the time of DD2's delivery (reminded my ob to prescribe it whilst he was stitching me up!) until she was 12 months old. I was happy for her to wean any time after 12 months so weaned myself off the Motilium. My supply certainly decreased, but DD was eating well (solids) by then and seemed satisfied by only the breast with no FF top ups. She continued to want the breast, particularly when she was tired. Er... she still wants the breast when she's tired!!

Take it one day, one feed at a time. You are doing a magnificent job!
