I actually dreamt that O slept till 6 last night, but alas it was a dream.
Think we need to go back to night weaning. Before we started it, he had just started sleeping through of his own accord, and I was worried that trying to reinforce it with night weaning put him back, so we stopped but whatever it was, the damage is done. If anything he's now worse because he's waking three times at night and for good at 5.30, although obviously still tired. I don't like causing him to be upset, and feeding at night was easier than the distress as well, but we're both getting pissed off enough with the situation for it to seem like the lesser evil now.
