Homeschooling and Monday hour one

Due to Covid, the kids are homeschooling. I have amended my calendar accordingly, reducing my tasks and giving them some time but it is always more demanding than I planned and the interruptions are constant while we are all at home. I feel like I am ‘Ask Siri.’

I am trying to keep to my schedule, which includes them but I do not feel in control. There are always interruptions. They are jumping upside down, they are hungry, they need to go out, they fight.

As a result, I feel overwhelmed and frustrated not to be able to follow my schedule, which is already very reduced. How do I solve this? I have spoken to them and I am teaching my boy to be more independent but that will take weeks.

I know I should be able to manage it all and it is not a problem but every evening I am exhausted and angry.
