DD2 is 9 weeks, she's been a great sleeper from day one. Apart from in hospital she has only ever woken once a night except on a rare occasion. Initially she was EBF and now I combination feed, but always from a bottle (expressed). Her daily intake is currently:
100ml/ 3oz(maximum, often less) at 7.30-8am ish breast milk
150ml (sometimes only takes 120ml) breast milk at 10.30am
150ml - breast milk at 1.30pm
150ml (sometimes more like 120ml) breast milk at 4.30/5pm
150-220ml formula/breast milk mix at 7.30pm
Attempt a dream feed at 10.30pm which usually only results in her taking 50-70ml of formula
150ml formula at 3.30am
I really want to encourage her sleeping through or at least waking earlier in the night so that I get a good solid 6 hours afterwards. I've tried leaving out the feed at 10.30pm but then she wakes at 2.30am and then again at 5.30am 
Any tips? DH usually does the feed at 10.30pm and I kind of still want him involved because otherwise it's all on me...
