My exclusively breast-fed six-week old just went from regularly waking to eat every 4 hours at night to sleeping 6-8 hours for the past 4 nights, a pattern I hope continues since he is still gaining weight well. This would be a very welcome change, except that I continue to wake up every 4 hours with painfully engorged breasts. I've been pumping one side and then the other a couple of hours later if LO is still asleep. I worry that if I don't regularly empty them, my milk supply will diminish but LO is now eating more than ever during the day. For those of you lucky enough to have babies sleeping longer stretches at night, are you able to sleep longer as well, and if so, has your milk supply been affected?
Re: Breastfeeding and sleeping through the night?
If you don't want your body to make milk during the night, stop pumping. BFing is supply and demand, but whether or not your breasts make milk at night doesn't affect whether they make milk during the day. Your boobs are actually pretty smart- nurse when LO wants to nurse (more during the day, less at night) and they will keep up, especially if you've already got the BFing relationship well established, which it sounds like you do. Just try to make it through the engorgement, and you will be fine.
Although I will say, if you want a freezer stash of milk, this is how I got mine with DS. I would get 8-10 oz at the 3 AM pump and had to buy a deep freeze when DS was 4 months old.
DS started STTN at 9 weeks. He would go to bed around 7:30 after nursing and I would pump (and still do) before I go to bed around 9:30,10. The first few mornings I woke up around 4 in pain from being so engorged. I pumped about 2 oz from each side and went back to bed. It was enough to make me comfortable again.
My supply has never been affected by him STTN and I agree with PP's, if you don't want to make milk during the night...stop pumping.
