Dear Susan,
I'sorry to hear that your son's fail to get up early enough.But don't worry.Here's some suggestions I'd like to put forward:
Firstly,you should buy a clock which can rings every morning for your son.The clock will certainly helps you a lot.
On the ather hand ,you should suggest your son to sleep early in the evening so that he could gets up early in tht morning.
I hope these measures will be helpful for you and your son.
Maggie
