Hey sweetie, huge hugs firstly..Hang in there things will improve. Firstly do you think the paci is a prop for your LO...do you think that she is NW because she loses it?
The other thing I am wondering is why you think she is doing the 2 to 1 transition, she may well be on the way it just seems a little early to me (but I'm not an expert and you not trying to suggest you don't know your LO 'cause you do
).
Is she teething at the moment 'cause that can cause lots of NWs and problems with settling where there were none before. With our LO it also seems to make him tired early but still not quite ready for sleep (I'm watching him AND the clock a lot at the moment!!).
Ok I'm not sure about using WI/WO with shush pat and paci use but perhaps you would be better using gradual withdrawal if she really gets upset when you leave the room. Remember absolutely no eye contact with her while you are in there and as little contact as possible. I found when doing PU/PD with my LO my presence was too stimulating for him and I found him too frustrating jumping up every time I put him down (this does pass by the way) so WI/WO was the only answer for us!!
If you think it may be teeth, try teething gel, there are herbal teething tablets and a dose of Tylenol/Panadol at bed time can really help. I don't like medicating my LO if I'm not sure there is a problem, but trying it once may answer some questions for you if you are wondering about teeth
If you think that the paci is becoming a prop and don't want to do PU/PD you could always try gradual removal
Good luck sweetie, hope you get some more help soon
Hugs
