Mine hardly does car naps either, unless he is super tired. I wish he would nap in the car though, as we always have to get him home for nap.
Jessmum46, 10.75 ONS is really good at this age, especially if it was after a nap. I know your LO probably needs at least 12 hours total, but it could also be sleep needs dropping. Ours suddenly dropped around 28 months. He was giving me 12 hours, then it quickly reduced to 11.5 and now at almost 32 months, we're about 11-11.5, but mostly 11.25. He did a lot of 12-13 hours those three weeks I didn't give him a nap, but that quickly changed and now sleep is the same about with or without a nap, so either way he sleeps the same amount.
My Lo was wiped out after preschool. He did 10.75 ONS last night, so after his 45 min nap, we got 11.5 hours total today which is better than his average. He's eating his bedtime snack right now and I'm about to put him to bed. I hope everyone's LOs sleep better for them this weekend!
Rachsk8, sounds like your LO handles no nap pretty well. May just thrown in the occasional catch up nap to curve the OT. I wish mine would consistently sleep 11-11.25 without a nap, but sometimes he really cuts it short, so I know OT begins to kick in. If he was consistent, I would feel ok dropping his nap completely.
