Just rereading the above and with reference to his temperature and bowels both seem to be normal, as is his appetite. I'll stick to nurofen from now on and try the pillow under the mattress.
When this happened before, end Nov, it carried on for 4 weeks, then one night he just slept through and looking back I don't think anything helped, he just got over it.
I have been trying different morning nap times although largely keeping the afternoon nap the same, 1-3pm. Yesterday we tried 30 mins am, 1 hour pm. Today we've dropped his am nap completely but will stick with the 2 hr pm to see if that has any affect.
I'm finding this morning nap hard to judge, he's been really happy during the last few days so although I assume he is OT there's no signs. I know hes the age when we reduce these so im foccussing on that although i know maybe he could do with the extra sleep, what do you suggest?
The 6.30pm bedtime is def working better though, no more miserable bedtimes now that we were having for a couple of weeks.
As for him being UT when this started, maybe that's a possibility but he's at nursery 3 days a week and on avg has only 1 hr to 1.5 hrs sleep those days and that has never impacted, positively or negatively on his night time sleep and he's been there since he was 9 months old. His bedtime used to be 7.30pm before this so he was getting a little less sleep during the night before.
If there's any more info that I can provide to help assess this then let me know.
