So update on today, he ended up sleeping for a total of 1hr50 with no resettling and has just had 3hr5 of A time and gone down to sleep without much fuss at all. He was pretty much asleep when I laid him down so maybe exhausted from the strange day.
No, not premature! Only early by 4 days and he's a fairly robust baby, didn't lose any birthweight when he came home etc. When you say high sleep needs, what are the indications of that?
I'll try 2hr45 A time tomorrow, do you think? Do you have any ideas for how I keep feeding him the 4hr schedule with this? Just keep feeding him when he wakes, I guess? Sorry if this is a silly question. I'm doing BLW so he's not really reliant on solids for sustenance at this stage.
