While at home during the week I don't feel the let down sensation at all on it's own unless in the morning before she wakes up. I feel it as she is nursing. But while at work, I feel it throughout the whole day. Does this mean I should be pumping more frequently?Or should I just keep doing what I am doing. 8 hour shift I pump about 2 sometimes 3 times, 6-7 1-2 times, while 4-5 hours is once. I try not to go longer then 4 hours between pumps, my goal is 3 hours, but sometimes it doesn't work out. She is 4 months by the way. At home she literally does not have a shedule. Sometimes it's every 3-4 but a lot of the time it's just random. I look at the clock and see it's only been an hour or so.
