I am pumping full time as my baby is a premie. She is 7wks old. I hear the more you pump the more supply you get which is great. However, do I need to keep up with it i.e every 3-4 hours? I find it quite controlling and feel I have no life sometimes i.e when I go out I have to be back in 4hrs the latest. Will it do any damage if a go out for the day and not express. Will my body store the milk for me for when I arrive (this will only be a one off) i.e once every 3 wks or so. I just fear that my body might be upset and start reducing my supply if I play games with it. I have been invited to parties, wedding, etc but have to express every 3-4 hrs how do I do it?
