I have a 5 year old son and a 3 year old daughter, they go to bed at 7pm and have been waking up, lately, at about 6.30am but sometimes as early as 6.00am. I've been making them go back to bed because they always used to wake up at 7.30 ish but I'm thinking 11 and a half hours probably is a fair amount of sleep. They are definately tired by half 6 and sometimes even earlier. Just curious at wot times or how long ur kids sleep??
