Just wanted to offer sympathy. DD had seriously wacky sleep after I stopped begging for naps (didn't work lol) around 2yo. She inclines towards super early rising, which I do prefer but whew. But by around 3yo it settled and then she could read so late or early she'll be pretty happy while we sleep... After coming in to say good morning, waking me up :p DS2.5 loves to sleep more than she but he's starting the late night thing too now. I can see him dropping the nap soon.
