DS has been sleeping through the night for over a month now (7:30pm-5:30am) - but I am still very full & hard in the morning. Fortunately, I'm not as sore now as I was when he first started sleeping through - so my boobs must be making less milk overnight. I find I am ok until 5:30 - but if he sleeps longer than that, I am lying there waiting for him to wake up because I am sore!

A couple of suggestions
1. Hawksey - Have you heard of booby bibs? (google it). I wear one of these now instead of a bra/breastpads. It's not perfect (I do still leak through every now & then) - but much more comfortable & most nights it's great (I just wear it under my PJs).
2. Try to let your boobs get used to the longer time between feeds, so that you produce less milk overnight (although if you are really uncomfortable then you'll need to feed bub/express)
3. Shower in the morning after your first feed & massage out any lumps that you feel (I still get lumps in the morning sometimes - my boobs are still extremely full when I wake up!)
