yup yup yup...very...slow... daughter..., got one of those myself. :) She is almost 21 now and she is STILL slow. No amount of pressure I put on has ever helped and in fact, I SWEAR, she moves slower if I pressure her to hurry. I have concluded that it has something to do with the organizational process of her thinking. If I could raise her over again, here is what I would do:
Get her a notebook that is her planner. Let her decorate the cover with stickers, pick a cover she likes, etc. One page a day that stays in the notebook. Each evening, have her make a list of tasks/responsibilities for the next day. If mornings are your only problem, you can have her just list those things. Help her to estimate how much time is needed to do each thing. Have a clock with the minute and hour hands available. (A lesson in time management and telling time all at once!)
With your help she lists each item, in order that they need to be done, and as she does them she crosses them off of her list. This puts her in charge and fully responsible for herself. More importantly, it teaches her to organize her time and her tasks. I nagged my daughter a lot and did many things for her in the interest of "hurrying" and she never learned these valuable skills.
PRAISE HER PRAISE HER PRAISE HER when she gets everything done, on time, without you having to remind her or rush her. At the end of a week when she has done it every day, you can give a reward if you want to. (I don't recommend that unless it is just special time with you because kids should learn to do things and just be proud of themselves and the accomplishment is the reward without always expecting to "get something". That's the other thing I would do differently if I had another chance at raising my daughter...)
