22 months. But the upside is bedtime got a lot, lot, LOT easier and earlier.
It took a while though -- the transition wasn't overnight, but in the end, it was obvious she was not needing to nap anymore, so I stopped trying to force it, and her bedtime gradually got earlier and the time it took to get her to sleep at night got shorter too.
The difficult part initially was that in between afternoon time -- around 4 or 5pm, when she started getting sleepy, but it was too late to nap (else she'd be up until past 2am) but still too early to go to bed, so we had to use a bit of distraction for a period of time some afternoons, or she'd catnap (a 15-20 minute little nap in the car, for instance). And that would rejuvenate her for a few hours. Anything longer that late in the day though was a disaster for nighttime sleep. So in the end, we stopped trying to get her to sleep in the daytime at all.
Now she sleeps 12-14 hours every night. Which is great.
We do have "quiet time" on days when I'm exhausted, but I make sure it's early enough in the day to not impact her nighttime sleep.
BUT some toddlers go through a nap disruption around the time they get their two year molars in, so it might be that's what's going on with your LO. Or a growth spurt or developmental change/stage.marshapn
, to answer your question about getting a reticent toddler to nap, I have to say it depends on whether the toddler still needs the nap, and is sleepy and physically able to nap. From your initial post, I'd say it sounds like your toddler is done with naps, honestly. At least for now. Some do give them up and later on start napping once more, though that hasn't happened with us. But if I were you, I'd stop trying. Put yourself in her shoes: if you weren't tired and someone wanted you to nap, could you? Probably not. So maybe try a compromise of quiet time instead. Have her on the bed, or in her room, but no TV or flashy toys -- just reading books, etc., quietly.
Give it a few weeks and gradually push her bedtime earlier. Don't do it in a large chunk, but just 15 minute increments or so. And see what happens.
Some toddlers will react to the new routine really well, and may even wake early but go back to sleep for a few more hours (that's why ours typically does). Our ped told us not to stress over it -- as long as they're getting the total sleep needed, some toddlers simply were okay with it being in one big chunk, instead of broken up into naps. You'll be able to tell if that's the case pretty easily I think.
