I've been reading threads in this topic but hoping to get some advice.
My 15 week old used to nap really well in his bouncy chair (among other places) until a couple weeks ago - he'd stir, bounce a bit with that motion, fall back asleep again - but now wakes completely after what seems like 26 minutes, which I'm guessing is daytime his sleep cycle duration. I've been trying the technique of bouncing through the transitions and it works kind of inconsistently right now (mostly I can get 2 in a row, but naps of 1.5+ hours are challenging).
He sleeps roughly 12 hours overnight, sometimes with 1 feed in the early hours and a feed around 4/5 am where he sometimes takes a bit longer to drift back to sleep, then up for the day around 7.
What I'm unsure of is how hard to try to extend naps right now, and whether 4 or 5 really short naps are "okay" for him? I understand that I want to teach him the pattern of longer naps so that he can learn to do it himself when he's developmentally ready to do so, but is it worth starting that relatively "early"? Or is there a number of "longer" naps I should be aiming for in the day right now? And how do I adjust wake time (if at all) based on nap length on a given day? It seems that no matter how early I try to send him off he nods off right around 1.5 hours after his last wake up (so can't eg. go earlier because his last nap was only 26 min).
