Hmmm I wonder if the reflux is having something to do with this. When was the last time her dosage was checked?
I too think you might have to go with the 6am wu for now. Remember you're putting her down for bed around 7pm so 11hrs ONS is completely ok and just all what some bubbas are capable of. Mine included. Once we get a stable routine on the go and find what works, we can always shift the whole day so BT at 8pm with a wu at 7am later down the line, so all is not lost ok?
I also think you're getting towards the 3-2 transition. This is a time when LO's increase their A time pretty rapidly. Remember, you have been working on low A times for her age and considering she's sleeping so well at night we do need to look at her total overall sleep in one day yk?
All these early morning NW's are screaming UT at me, especially as she's happily chatting away. She may well be getting OT by the end of the day, but again there's no NW's where I'd usually expect them if this were the case.
Ok, so plan. Let's do wu at 6am. Leave her for around 15mins (I always think that it's nice to have that wu time on their own for a bit). Then let's move all A times to 2hrs 15mins for the rest of the day from 6.15am. So first nap at 8.30am, etc etc. Then I would use w2s around 25mins after she falls asleep. Have you done that one before? Did I mention it?
I know you're finding it difficult atm, we all do from time to time, but I'm here to help and I promise it will get better. We have to keep pushing that A time some more I believe to get rid of all these silly cat naps xx
