I'm sure you're all sick of my updates but I don't want to leave anyone the wrong impression if they refer to the thread later!
It turns out you ladies were right and it *is* UT, we just weren't extending the A time enough to see a difference at first (and were probably also disturbing her mantra). Last night we did 5:05 (up from 4:40) and she mantra'ed for ten minutes before getting herself to sleep so we'll keep extending till we hit the perfect time. No NWs and she only needs the one bottle of milk if she gets to sleep so quickly so it doesn't feel like so much of an issue.
It was so lovely having an evening yesterday and we're feeling much more ready to introduce a new baby into the mix of things. Still waiting on that one though
