Hi again MoC,
His schedule is mostly working well (save the lack of catnap) :-
E - 7am
S - 8.30 or earlier if he woke early
E - 10.30am or later if he isn't hungry
S - midday - he's usually really in need of this one and can go 2 hours
E - 2pm
S - 3.30-4pm - difficult nap, usually 45 mins. only
E - 5pm, only later if he sleeps 1.5 hours
S - 6.30-7pm, whenever we can settle him
DF 10-10.30pm
I can't change him at DF so we'll have to see if those Overnites can hold his last ozs in !!
TBH, we have tried "cold turkey" last few nights but he can fuss for ages, sometimes sleeping in between which makes him v.tired by 7am. We'll definitely do it again over a w/e when DH can help ! Paci would be good if it worked...and like you say, the watering down seems futile as he used to take 2-3 oz at 3.30am (for ages when we first tried weaning at this time).
Guess that leaves me with w2s which I'll try for a good few nights. The naps seemed to self-correct as when I stepped back from doing w2s after about a week he extended his naps all by himself. This waking is a little more entrenched though so we have to bite the bullet...YIKES ... he can yell like a good 'un !!
