Sleep definitely helps! I have a 6 and almost 3 year old so it is definitely better now.  Both wake up by 7am, but my 6 year old plays with the 2 3/4 year old in the mornings and doesn't bother us while we sleep in on weekends. He knows how to pour cereal and milk for himself and her and we love him for it. The other plus is that he's in school all day and now she's in preschool half day.  Once you get to that point, things get much easier and more challenging in other ways.  Do whatever you can though to actually enjoy them because they really do grow up too fast!
