Hasn't napped in a while now.....but nap got as late as 2ish for 45-1h max for a 7pm BT (we never put down later than that, though when nap was needing to go she would take a long time to go to sleep). When we were having lots of no nap days, the nap days were just a 20 min catnap in the car around 3pm to hold off too much OT, with normal BT.
