If there's one thing I've learned about baby whispering, it's that most of it is in the assessment and planning and much less in the execution. It really is vital to have a game plan first rather than rush into trying to "fix" everything. I think first thing's first; you need to stand back and take a good look at what's going on
As I mentioned last time, a lot of "sleep" problems are actually routine problems so while it's great to try to tackle props (assuming the dummy actually was a prop and not just a comfort item for her), you won't get far unless the routine is also good. Hang in there, but it may take a little longer because it sounds as though you need to work out your A times.
In your first post, it looks like the amount of time she was up for was 1:30-1:45, except before bed where it was more 2:15, and she was feeding every 3-3:15. Is that right? Then when you started training, you suddenly jumped to longer awake times (2:05-2:25, and 3hr before bed) and longer stretches between feeds. It tends to be better to extend times gradually to allow them time to adapt, although if she'll happily go 4 hours between feeds that's good
You do seem to have gotten into the habit of feeding her very shortly before her nap, though, which isn't ideal as they need to learn to separate eating and sleeping. I would try giving her a smaller feed when she wakes around 5am so that she takes a more full feed first thing in the day. That'll set your EAS pattern straight, which may help a lot.
30-35 minute naps are generally an indication of overtiredness, especially when coupled with crying hard and waking soon after going to sleep or getting back to sleep. So the jump in A time seems to have made her OT. It looks like you need to pare back the A times a bit, try it for a few days (very important, as most babies won't respond immediately), and then see whether you need to bring them back more or extend them gently. It may take a week or so to figure out more precisely how much time she needs; about 2 hours is the average at her age.
So, putting that all together, your day would look more like this:
Wake 6:15
E 7:30
A
S 8:15-10:15
A 10:15
E 11:30
A
S 12:15-2:15
A 2:15
E 3:30
A
S 4:15-5
A 5:00
E 6:45 (a little less than 4 hours in order to get it in before bed)
A
S 7:15
How does that look? Has it given you any ideas?
Re: your question about picking up, at this age you can be using PUPD. If she's crying hard and not quickly responding to just shh/pat, you would pick her up until she stops crying, but no longer than a few minutes so she doesn't think she's going to sleep in your arms. If she shows signs of wanting to settle herself in the cot (like fighting you by arching, or trying to suck a fist or rub her head on the mattress), you would leave her in the cot or put her down. So PUPD doesn't replace shh/pat, it's more of an add-on for older babies, if they need it. There's a more full explanation here:
