Fantastic for the good night!!
I would actually try to push bt to 7, he could be able to stay awake for 12.5 h after a such long night, and you would have more chances to avoid a wu before 6... of course, if he doesn't nap!
As a rule, I would try to adjust usual bt as if we have a 11 h night the wu is not too early.
Yes! this does seem to be the case. I think it's probably more of a regression/adjustment period though (at east for us) than his actually sleep needs decreasing. Don't you
I am not really sure it is a regression. It is for sure an adjustment. It is already a couple of months that we have total sleep oscillating between 11 h and 12 h in 24 h total, so an average of 11.5 h per day. And he's perfectly fine with this amount of sleep, no sign of OT. So I think this is what we have. I've also read of many 4 yo that have a 11 h night without the nap, so it can well be that 11 h in total is what most have at 4 yo, and we are going toward there...
I miss 13-14 h total sleep per day (especially the 2-2.5 h nap that gave me lot of time on Sunday afternoon to nap myself...)!
