I don't know how much this will help--- as my kids are younger...
But to maintain sanity here - the kids get ready the night before.....My older two are 11 and 8 and they get their clothes and backpacks prepared before they go to be. (My 8 year old knows all three kids' school schedules and reminds his sisters when it is their library and gym days)
I still get the clothes for my 6 year old --- but since she decided that she wasn't going downstairs to get clothes - she can't complain about what I (or her dad) put out for her.
Unfortunately, alarms clocks don't wake anyone in the house except ME! (Not even my Dh -- so I have to wake everyone!)
The one thing that motivates my youngest ---Eggos...I found that when I got those for them, my kids wanted to make sure they had time for a 'sit down' breakfast......
I don't know if you can lure your kids out b/c of food or not.
I sure am not looking forward to those years.
What are the consequences at school if they are tardy?
(I really think the start time of high school may really be too early for some kids developmentally. If you look at some of the research on adolscents -- they don't do well in the morning and would do better if they went to school later in the day. I actually think one of the peds. once suggested that teen think better in the late afternoon and early evening--- Not that anyone will adopt that school schedule since it doesn't work for adults and sports. So you might keep this in mind-- that maybe it isn't just motivation that is keeping them dragging their feet......The developmental issues should improve over time- but that doesn't help you to survive NOW)
