DD three weeks old, I have been prescribed donperidone as lack of milk supply. This seemed to work brilliant at the start of the week, last night and all day today very unsettled has fed on and off all day falling asleep the breast after about 15-20 mins i have then nursed her for a little before putting her down in her cot she stays asleep for about 10-15 mins then wakes very very tearfull. I am really really hell bent on breast feeding but starting to wonder if there is not enough milk supply ir that we have just simply hit a growth spurt any suggestions? I am also having difficulties in expressing using electric pump
