We have the exact same problem with EW right now! Since we moved from 3 to 2 naps (succeeded just a week ago, before that it was a couple of weeks bouncing back and forth between 3-2). But I think that if LO sleeps from 7 pm until 6 am, he still gets his minimum of 11 hours at night? We're happy about that. When we started the transition he went to bed at 5.30 pm and woke 5.15 am - so 6.30 pm until 6 am is an improvement, at least for us.. I believe that when LO can handle more A time, the bedtime and WU will eventually be later?
