I have read your replies HelloKittyGirl and I'm going to tell you this.
My Uncle says as a child, their DM got his sister, my DM, off from doing PE at school and my DM used to spend the time in the library, which she ''preferred'' to be doing...
Fast forward to today, my DM is well into her 80's and wheel chair bound. The hospital where she lives has to use a medical hoist to be able to get her to stand, move from the WC to toilet and back again, and also to assist with getting her in and out of bed.
Ever since I can remember, Doctors have been telling her to exercise more, which she didn't. The Doctor was always wrong!
I have sat with her in one of our major hospitals after a fall, to hear specialists say she needs to exercise more. Once back at the hospital where she lives, she ''forgets'' this advice and if reminded of it, says they are wrong! These are specialists who have spent years studying to get where they are career wise.
I have also experienced DM, getting craftier as she gets older and if she doesn't want to do something, she out right will not do it. So at a young age, Mum was taught by my Grandmother by letting off her PE, that if she didn't want to do something, she didn't have too. And that has stuck with her for her entire life!
My DM won't even move her feet to put her slippers on, she expects that I, or a nurse, will bend over and do it for her while she looks on. However, while getting herself along in the wheelchair, she is quite capable of using her feet to ''walk'' the chair along.
She now has a permanent sore on one of her ankles so is now wearing a pressure stocking. It's not healing and her lower leg is slowly turning purple. I suggested to her she needs to start exercising, and the hospital agrees. However with the chair-based cycle device, she could use, she will not try to turn the pedals...
So before you start making excuses for your Daughter to get out of PE, think about what else you are setting up for her to avoid long term. Sometimes you have to accept that some things are done for more than one reason, and its not always obvious why.
Participation, engagement and social cooperation for starters.
