Hi trimbler, we have done 10.5hr but that was with a late WU, on NNDs the earliest we have pd is 6.30 and that was just once and she did 13hrs to our surprise. Before NNDs we never had nights over 10.5- 11hrs. She's done 3 NNDs in a row a few weeks ago and she did great 1st day, slept 12.5 hr, no nw, day 2, slept 12hrs 3 nw, day 3, slept 11.5hr, 8 NWs. However she probably should of gone to bed earlier. She was touchy on day 3 but ok on other days. I think the 30min naps are putting her into a UT/OT loop. She has short night and wakes tired, her nap refreshs her and she's happy all afternoon but not tired for Bt, i might be wrong but that's the only thing I can think it is because the last few days she will take a nap no problem, even after only a few hours awake due to being sooo tired but bedtime is a battle and we are getting a lot of NWs, which I'm guessing are from OTness? After so many short nights. She's 28 months now, but nap refusal/taking hours to go to sleep, occasional NNDs have been going on since her 2nd birthday. Sometimes i question if it's the 1-0 and that maybe she's just in an OT cycle but then she wouldn't fight Bt after a nap?
