Dd is 12 weeks and I've expressed exclusively for her since she was born six weeks prematurely. I'm expressing every 3-4 hours and twice overnight and am just about meeting her at the moment. The problem is I have an old child and will want to go out for the day over Easter here and there. I also have a wedding at the start of May where it will be very difficult to express all day. If I reduce down to expressing five times a day - and at least once at night - will it dramatically reduce my milk supply. I could do 9am, 4pm, 8pm, 12am, 4am I just need more time in the day.
