Ok, most of those NWs sound OT to me.
Stick with that first nap no earlier than 9am for the next few days and lets see what happens - what he's used to is that first nap getting earlier if he wakes earlier so keep it at 9 so its not shifting with him. It can take a while to get his body to adjust to it. Until you're consistent for probably a week or more given how long sleep has been awful, he cannot begin to self-regulate.
Thanks.
Yesterday was:
WU: 5:45
A 3h15
S 09:00-10:15 (resettled after 45mins)
A 3h15
S 13:30-15:00 (woke after 45mins, would not resettle so co -slept remainder as we were at my parents house in different environment)
A 3.5hrs
BT 18:30
NWs: 20:15, 01:30, 03:00, 04:00, 05:15
WU: 06:00
The first 3 NWs were where he had rolled into hiscot bars and woken himself up too much (a problem we are having at the minute), the others he was just really unsettled for some reason. He pretty much just dozed and tossed and turned from 5:15-6:00.
However with a later WU I will definitely be able to do our 3rd day running of a 09:00 nap.
