LOL Cricket, He not only gets up alone and entertains himself but I taught him to make coffee! We figured since he was the first one up he could have coffee waiting. :-) He doesn't however practice math facts or do anything other than watch tv and play his DS. I asked him this morning how he could be so quiet when he is with himself and then start talking and being silly and wild when we got up. He said he likes the quiet in the mornings and finds it relaxing.
I think we got him started on being on his own in the morning because the rule was he couldn't get up until 6:30am but then we worked a deal where he could get up whenever he wanted if he was quiet enough not to wake everyone. He tends to be up between 5:30 and 6 everyday. What would happen if you do not go downstairs with your DS but made a similar deal?

BTW - The quiet boy from this morning is now on my last nerve because he has done nothing but talk, sing, make jokes, pounce on his sister and do cartwheels all morning! Oh, he did manage to do his math (we homeschool) and we all worked on an Earthquake project. Why did I pick homeschooling? I am tired!

Good luck getting some morning time!!
