My ebf baby (4 months) has started sleeping through (7pm to 7am) and it is causing as many problems as it has solved. I am no longer feeding in the middle of the night but my boobs don't seem to realise this and the engorgement is so severe that I have to get up to express to be able to sleep from the soreness. So instead of getting more sleep I am getting less with all the faff with bottles and pumps in the middle of the night! How long does it take for the breasts to adjust to the new routine? It's been a week now.
