Eeek! Be very VERY careful just giving up on her pm nap, especially when her am nap is so early. You will end up with a very overtired little monkey and it's a bloomin nightmare to get back from that state (I think it took us 8 weeks in total
) IF you're having EW and NW then you might be a little way down that road already
You need to have a look at the 2-1 transition thread - there's lots of us on there trying to get through this particularly sticky phase and lots of different experiences about what works and what doesn't. It's at:
https://babywhispererforums.com/index.php?topic=98011.0Unfortunately the BW book makes it all sounds very straightforward, when for a lot of people it just isn't like that.
Basically there are two routes you can take:
1) Try and shift the am nap by 15 minutes every 3 or 4 days til you get it closer to midday whilst doing a VERY early bedtime (like 5pm) to avoid getting OT.
2) Limit the am nap by waking your LO up after an hour to see if you can get a pm nap happening again. If not, then try waking at 45 mins, or even 30 mins.
I think the second option is your best one as even with a very early bedtime, that's a very long A time between nap and bed and OT is a very likely consequence.
There's loads more info on the 2-1 thread and I think there's a really useful post in the FAQ too.
Good luck!
