1:45 S for 35 mins (tried resettling with PUPD but it didn't work, because honestly I don't know what I would do to settle her as she is waking. I think I would be more of a distraction. If you have ideas I am willing to try them).
Ok, so I am having anything leap out at me as an obvious explanation for that 35min waking. I found that whatever I used to help LO fall asleep was helpful in getting him back to sleep so shush/pat or similar. Hold through the jolts was also useful at times. Is she waking and screaming straight away?
2:20 W ( breathing quickly the whole time awake)
This is interesting - does this happen often? I just wonder if she was scared? Certainly the developmental leap around this time involves LOs learning about distance and I found personally that my DS would stir and then wake and be very upset if anything was different than it was before he went to sleep (mum gone, white noise off, etc. - so if I had been there with him when he fell asleep, I could resettle if I was fast enough but often he was too worked up by the time I got to him.
Am I right in thinking you're not feeding when she wakes at ~3:30 and hasn't had a NF since ~10pm? Its reasonable for her to be feeding X2 overnight, so might be worth feeding. Having upped her solids may be what's causing that hunger - solids has less calories than milk, so actually the more she takes and the less space she has for milk in the day, the more she may want to feed at night. Is she having solids in the evening? Sometimes babies wake in the night because they can feel the food moving through their gut and its 'new'. I've seen a few babies go back to sleeping as they had previously just by taking out night-time solids and adding them in again a few weeks later.
And when I do feed her I only give her a min or 2 of bf and she doesn't seem to want anymore or seem vigorous at her sucking so I don't think it's hunger although I have upped her solids quantity.
She may not need to be sucking as vigorously at night given your supply and thus flow is highest at this time.
3:30 W did PUPD ,she settled , stayed awake until 4:20 then cries more , gave her Advil in case teething and she seemed hungry )7:30 am heard her7:55 E9:55 S for 30 mins (she seemed to get more cranky as time went on; tried PUPD for 30 mins but didn't work)
Is she trying to sort out a new milestone? Crankiness can be from sources other than tiredness - eg. frustration.
6:55 heard her 7:15 E9:35 S for 1h10 ( decided to follow her cues a bit more after the day before she 30 min morning nap)
This here is really obviously UT - I'm not sure what the deal is with the 30min nap the day before off a similar A time. I think keeping those A times up at 3hr is going to be your best bet - certainly that's where you're getting your best naps. Keeping it consistent even after poorer night is important for discouraging those long wakings.
