Ok hun looking at your EASY it looks pretty good, only thing that I do wonder is if the last A time to BT is a little long at just over 3.5 hrs. Average for an 8 mo is 3 hrs and 3.5 hrs for a 9 mo. Just thinking that this might be making your DD OT by BT causing the frequent NW. Have you tried an earlier BT, say 7pm?
As for feeding in the night I agree that it is probably a good way of getting more milk into your DD so if you are happy to still feed in the night by all means carry on. Do you not feed your DD milk before BT? I wonder if she would take a bottle as part of your WD routine (not feeding to sleep!) but so that she has a fill before bed. My DD always had, and still does have milk before bed.
In terms of confussing your DD it is important to be consistent yes, but if you choose a time that you will not feed before and use PU/PD until this time then your DD will soon understand that if she does wake before that time she won't get fed. So if her last feed is at 7pm, you could decide not to feed before midnight, for example, and then not again before 5am. Or whatever times you think are appropriate, if you only want to do one NF you could maybe not feed before 1am and then not again until morning. Only you can decide this really. What is important is that for the other NW you use shush/pat or PU/PD to resettle your DD. Does that make sense?
