Self-help advice for parents now trying to teach kids at home:
My daughter has special needs; it’s taken me a long time to realise that she could ALWAYS take more attention, more energy and more help, no matter how much we give. There's no point feeling guilt about not giving more, because there can NEVER be enough. we have to be OK with doing what we can sustainably do.
The same goes for teaching your kids at home. There can never be enough, so you have be OK with what you can manage.
