Son, 9, AuDHD with a large dose of PDA in the mix, cannot function in the mornings before ADHD meds kick in. He is "tricksy", a "funster" (in PDA parlance), constantly not doing what he's supposed to and doing what he's not supposed to, making offensive noises, trying to annoy (mostly me, but for a dopamine hit he's quite happy to also annoy his dad, and the neighbours). He was also like this at school, to the point of getting kicked out at age 6. He is now homeschooled as we have no other options (we are outside the UK). I hate homeschooling him, but the only other option is the correspondence school, which is absolutely dire and is effectively homeschooling anyway because it's so inadequate.
Some of the behaviour is that he sees toileting and eating as demands to be avoided. Some of it is probably that he resents being sent to the toilet because he doesn't have the interoception to work out he needs to go; and that the sensory demands of eating before ADHD meds have kicked in are too much. School was definitely too much for him.
The only way I can get him to eat is to ignore the constant barrage of antagonism, and literally hand him every single spoonful, while holding a novel for him to read. This takes hours (2 hours for one piece of toast and some fruit). By the end of it the meds have kicked in and he's ready to be human. But this is 2 hours of unpleasant stress that could valuably be used on other things.
The PDA antagonism is also making me sick with stress. I have developed IBS, migraines, high blood pressure, fast heart rate, angina. Everyone tells me to reduce sources of stress. I point out that the source of stress in my life is one i can't get rid of and am stuck with, 24/7. THere's no respite care and family don't help. My husband works 24/7 as the sole provider (and because he wants to escape - frankly I don't blame him).
