Hi S.,
I also have a 6 year old girl, and I think that it is a good age to encourage their independence and sense of personal responsibility and accomplishment. They are in school now, and are being expected to accomplish tasks and be somewhat independent while they're are at school, so it's probably time to help them further develop those traits at home, too.
Our routine is that I wake my daughter in the morning, and ask her to start getting ready. Her before school responsibilities are to: get dressed (I lay-out the clothes the night before), brush her teeth, brush her hair (then I style it), make her bed (to the best of her ability, anyway), feed her fish, and eat breakfast (which I make for her, although she likes to get her cereal and milk for herslef if that's what she is having).
Sometimes it is probably more of a pain to have her get herself ready, as 6 year olds often get distracted, or they can't complete some tasks as well or as quickly as Mom could, but I think that it also builds character and a sense of personal responsibility which are good things to start early. Plus, like you, I also have a 2 year old and myself to get dressed as well, and I need all of the help that I can get some mornings! If you do decide to start giving her some morning responsibilities, I think that it is important to remember to lay out a set list of responsibilities that she will have every morning, and maybe even make her a chart of them to help keep her on track. If she's anything like my big girl, she will get distracted sometimes or dawdle and do things so much slower than you would, and you'll still have to help motivate her and keep her on track if you want to get to school on time. It's also important to keep your expectations reasonable for her age--my girl won't be able to make a bed like I prefer it to be (I make sure to recognize and praise her greatly for her best efforts on it). Six year olds are still developing their muscle control in their hands, so she may still need help cutting those waffles (but maybe she could get the syrup out for you). But, when my daughter gets her morning list done with time left over, I give her free play time before school and she is SO happy and proud of her accomplishment!
