We've been tweaking her naps since January...trying different naptimes and lengths, went through a couple of weeks of no naps (still had a "rest" time) and then when she finally started sleeping again I cut it down to 45 min max unless she is going to have a late bedtime. I really think this is the beginning of the end of her naps, but I want to maintain a quiet rest time, so I still will keep putting her in room every afternoon for that, whether she sleeps or not is up to her at this point.
