My lo is three weeks old and I've been trying to pump during the day but I'm struggling to get anything at all. I've tried different sizes for the pump and I've been eating oatmeal like nuts. I go back to work at the end of the month. My plan right now is to keep trying to pump but if it doesn't work then I will have to supplement while I am at work. Anyone do anything similar? I'm really worried! Also any suggestions would be great!
