Suddenly my dd started to get up early and sort herself out really early. It turns out it was from watching "morning routines" on you tube. At one point we had to nick her sleep as she was setting it for about 5.45 It's got to be worth a try.
My Ds is crap at getting out of bed, and would crawl out at 8.30 if he could. By 7.30 most mornings I will have woken him twice, called to him several times so I go for the brutal option- nick duvet, and send the dog in to kiss him. He complains, but it works :D
You can get alarm clocks with a vibrating pad which goes under the pillow. I use it for my dd who has a hearing loss. It also has bright lights and is very loud, but she has it set on vibrate only. Google alarm clocks for the deaf. However dd2 is hearing but rubbish at getting out if bed too, I have no answer to that part
Ds(10) takes a long time to wake up properly in a morning. His alarm goes off at half six, which he turns off and ignores, but I get up at quarter past 6 so I just keep knocking on his door/ calling from my room/shouting upstairs whilst getting ready and do so every few minutes til he eventually surfaces downstairs just after seven, to leave at quarter past.
But I don't need him to have breakfast before we leave as my dad sorts that so I can be in my classroom for 7:45.
Its not really a helpful suggestion in afraid but I just have to keep lightly nagging at him til he surfaces in a morning.
