Thanks ladies. Rough night. Woke screaming a few times before 10. Then up at 4am. Babbling til 5:10. Back to sleep til 5:50.
I had a lot of time to think in the wee hours of not sleeping.
First I realized she is definitely not ready to try one nap. She is so miserable in the mornings and could easily nap by 9 although I've been stretching her til 10.
Secondly, a short am nap just gives us a short pm or complete refusal.
Third, I was so enjoying the later schedule when I was aping the naps.
I think the hell of waking up at 4 BC of OT is just too much for me right now. The pro of aping the CN and am nap extention if necessary is that I get a consistent schedule and good nights.
So I've concluded that BC we're already in a mess with the 2-1 that to add dropping the aping to the mix just makes things too messy for me. She is just SO sensitive to OT and schedule tweaking takes months for her.
So for now, I'm continuing to do what zacsmumme has described as that is pretty much what I was doing before.
She goes down fine for the am nap 99% of the time. Then it's a 50/50 chance of whether or not she takes a good long nap on her own. And she almost never will take the 2nd nap on her own.
Thanks for the help. I hate feeling so flighty with me decisions but after really looking at the pros and cons I think my best bet is to hold tight to 2 naps and ap when I have to to save our night sleep. As a stay at home mom I have the time so I might as well do what keeps us all the sanest for now.
Hopefully when she's ready to do 1 nap I can work on independent sleep.
