night time engorgement

lynniecheer06

LO has been sleeping pretty consistently for the first part of the night for between 4.5 and 6 hours for about 3 weeks now.  The problem, is that unless I pump before I go to bed (which I have done a few times) my boobs are so engorged and painful they wake me up before she gets up.  The last few nights I've woken up about 2 hours before she woke up and had to try and go back to sleep.  Even with an occasional pump before bed, they are still very full (though often not as painful).  Anyone know about how long it will take for my body to sort out that it doesn't need to make as much during the first part of the night?  are there any tips to help the pain/engorgement?
