Ds who turned 2 last month, can go to bed anywhere from 9pm through to 4am. He is usually awake around 7am-8am, any later than 8.15am and I am usually waking him up to change him so we can take DD to school. On the weekends he might sleep till 8.30am, last weekend he did a 10am sleep in, but he still wakes 2-3 times a night...at least!
