Melissa, it tooks us months to get to 1 nap...very slowly
I think if you cant get the CN in you just need to stick it out with cold turkey. You are doing everything right.
I would however make sure that her nap is always at the same time every day so your LO gets used to taking a nap at that time. If she wakes early or sleeps in move the nap 15mins forward or later but other than that it is fixed. Give it 3 loooong weeks and cross your fingers

I tackled things a bit differently because Zac is pretty touchy when it comes to sleep. For me BT were pretty much fixed at ~7pm. If he refused a CN it was EBT at 6pm. I also refused to give him his nap before 10.30am but usually it was a 4.5hr A time. If I got a CN after the next 4.5 it was ALWAYS in the Car (GROSS) then 2hrs to BT.
Our days would be like this (usually WU and BT between 6-7) Ill do it for a 6am WU and see how it looks for you to ponder
WU 6
A 4.5hrs
Nap 10.30 for 1.5hrs+ (We were getting 2hrs most days. I NEVER woke him from this nap unless it hit 3 hours so he got used to the long nap)
A 4.25/4.5hrs
CN ~4.20pm based on 1.5hr nap or 4.50 after 2hr nap (He would actually only usually last 4hrs20 then drift off in car with his dummy and lovey)
A 2-2.25hrs
BT ~7 (7.15pm at latest really)
Without CN it would go...
WU 6
A 4.5hrs
Nap 10.30 for 2+ hours (If Zac slept till 1pm I knew I could do 6pm BT and 1 nap day IYKWIM)
A 5hrs or to 6pm (hopefully if got a 2.5hr nap or refused CN)
BT 6pm
EBT worked for us thank goodness. I got to the point when we were doing the CN every few days, or a few days in a row then not for a few...then he just refused over and over and his naps got shorter for a week. Then he got sick/teething and now its like it has fallen into place.
I must say our A times were longer before or no shorter than now. WU usually ~7am I pretty much do a set nap of 11.30-11.45ish and he will sleep no longer than 2.30 (I will wake sometimes) If he wakes earlier than 2hours we stay in his room quietly, this is usually due to teething pain. BT are still 6pm if EBT due to rubbish nap, or between 7-7.30 now for BT. Zac will fluff around at BT for a while sometimes...probably UT but we don't hear him on the monitor, DH just heard him when walking past, so until we get refusal etc I am leaving things as is.
Personally, I wouldn't cap your good nap. I know 1.5 is restorative, but you may find he starts to nap that long all the time if you start to cap it, this happened to me for a bit so I started over. As time went on Zac slept longer for the 'nap' that we kept.
Gemma - 1hr20 for us is always pain or UT so you could try pushing an extra 10mins after a few days? Great progress with longer than 40mins!
