Don't be quick to jump to the conclusion that the son can be in school. I had a cousin who was not able to go to school & needed round the clock care. There was no way both my aunt & uncle could work (even opposite shifts). My aunt stayed home with him. The care that he needed was on level with a newborn. He couldn't do anything for himself (literally). By the time he was 6, he needed to be suctioned every hour to remove mucus,etc. from his throat. He was barely able to swallow. He needed a feeding tube & needed to be fed every 2 - 3 hours.
My aunt tried working part time, but ended up so exhausted she ended up in the hospital.
They tried a bunch of different daycare programs set up for this type of situation, but the quality of care was awful. For example, Chris was suddenly having diaper rash problems, he was 4 at the time. He hadn't had those in years because of my aunt's care. She surprised the daycare with an unannounced visit. He was sitting in a poopy diaper. It had been on him so long it was dried to him. They finally found quality part time care for him, but he was 12 by that time.
