hey - hmm, no I think they are usually pretty straight forward - ie, 3 days for teething then back to sleeping through, they are medicated at night still in case thats it and they do seem to be going through a big couple of changes.....
there is definitely some nap resistance in there (used to self settle off to sleep in minutes - now its more like 4o mins) and only down for 45mins 2x a day.
really feeling for the mum - can you imagine being up awake for that long in the middle of the night!? its one thing comforting and settling - quite another when they wont even act tired!!
I did wonder about the ut/ot thing.....but they are already awake for around 3 hours and have extremely clear tired signals....
soo confusing!
