Until the age 2, we did nap from 11-1. Then had lunch together, giving us a short morning - out locally for a couple of errands or messy play. Then the whole of the afternoon after that. He managed from 1 until 7.30pm.
Since then... he's been too awake at 11 to go to sleep. So he now sleeps 1.15- 3.30 (but often 4). I HATE IT so late. Unless I am really organised, we don't get much done in the morning, to do early lunch at 12ish ( I don't like him sleeping on a full stomach). Or trying to keep him awake in the car so he can still have good quality sleep. So that means home to be able to prepare it. I feel trapped by the afternoon nap. But that's my opinion. I am getting used to it and having my lunch with him and I do like having those 2-3 hrs of Y time / get work done etc. But by the time he wakes at 3.30, got dressed, had a drink etc I don't feel like we get much done then either, because I have to be back to get dinner ready.
Sorry - I sort of hijacked your post with my vent. Go with what works for you and your child and your day.
