Well, of course I've spoken too soon... F fell asleep today in 15 mins when offered the nap: we are now offering him at home telling him he has to rest for 30 mins, today we put a timer for 30 mins and he fell asleep in 15 mins, so he clearly needed the nap after 3 nnd. I let him sleep 1 h and woke him up (it was already 3.40 pm). He was still tired, so probably needed more, but I was sure this would have impact on bt. However, my plan of putting him to bed early due to clock change didn't worked and he ended up in bed at 9 (normal bt with the nap).
but if he's up earlier ie 7am i'd do 6.30, so ends up a much longer day. It takes out all the worry & guesswork, saves me stressing, & if he's tired we just have to suck it up & power on through. And yes if he got up really early eg pre 7am then i'd def make that a nap day. And if he's had say 1-2 nnd's & got up at 7-7.30 i'd prob still offer the nap just in case.
I think that, as they become older, they are starting managing a 12 h or even longer day. We often do a 12.5 h day on nnd, and F handles it very well and sleeps well in the night. But he needs napping every few days.
I think these kids still need napping sometimes, even if they have shorter nights some nap days, but having the sleep spread between nap and nights help them keeping OT at a bay.
Aishi, I think there are some LO that can't do nights longer than 12 h, my DS does 12 h absolutely max, and he's more around 11 h.
Kara, I think that offering her the nap, and letting her taking it or not, could be the right thing to do. We also have a moment of tiredness between 4 and 5 pm when F doesn't nap (and he falls asleep in the car if we are our in that period), then it passes and he's fine till bt.
