My 15 week dd just slept from 7:30 til 3:30 !!! But man, didn't my boobs know about it! This is probably just a one off and we'll be back to two hourly feeds tomorrow night, but for future reference, what are you supposed to do about your boobs when they start dropping feeds? Do you express or leave them?
Boobs just get used to it. You could express a little if really uncomfortable. Mine just leak so it's not a problem! Hope you enjoyed your nice chunk of sleep. We've had a few like that (not tonight though!) with 12 week old DS.
