I'm curious whether your toddler/preschooler stopped napping abruptly or gradually, and what you think is the better way to 'navigate' the transition period - a regular early bedtime without naps versus occasional naps with changing bedtime. Background: My 3.5 year old had been napping on and off for the last few weeks (would go 1-2 days without then 1-2 days with nap). When he missed his nap, I'd put him to bed by 7:15pm, if he napped, by 8:15pm. This last week he's been refusing to nap every day and I haven't pushed the issue at all given his age. However, some days he is clearly exhausted by 3:30 or 4pm (too late to nap) and by bedtime is wired up and overtired. He's up between 6 and 6:30am regardless of bedtime. I'm afraid this 'cold turkey' approach that I'm going along with is leading him to become overtired, but perhaps this is a short-term problem that will correct itself with a consistent early bedtime. I would love to hear from others with experience dealing with this difficult transition period.
