They are 4 and 2. I put them to bed at 8:30 pm, but they stay up talking to each other and playing until about 10 or 11pm. After constantly going in their room every five minutes saying, " be quiet and go to sleep" and them still staying up that late, I decided to just let them be as long as they didn't get out of their beds.
So, now I wake up at 6am, do all of my chores before they're up. Since I have no chores to do, I can give schooling my undivided attention.
As they get older, I will get them up earlier.
