Hi op, many people on here are biased to home ed. Their replies say it all. You are not limiting your children's choices or lives but home ed. It is an enriching experience. And you are putting their interests first as your children don't need a stressed, sick and anxious mother.
I home educate, you don't need to do 6 hrs per day as thats for a classroom of 30 or 40 children, not 1 to 1 or self directed study.
You can home ed in many different ways and there are lots of different ways to learn.
You do not need to follow the curriculum as that's just the current best way of educating hundreds of children per school year per school. You only have 2 children to worry about so educate them according to the way they learn and what they are interested in.
Many people have been quite mean about your commute. Great for them if they can cope but you have said repeatedly that you cannot. They don't seem to be listening to you.
So do what is best for you and your children and home ed can be great for many children.
People are showing their anti home ed bias in their replies. Your children will not lose out by not going to school, if they gain socialisation in other areas and if they have a happy non stressed mother.
Ring the lea and take them off the roll, state your reasons and prepare your new home ed week.
I do an overview per term of what I'd like to achieve and what classes and lessons we will attend including day trips and topics.
I then do a week by week lesson plan down to the pg no of any text books and workbooks.
We don't always stick to it but it's a guide and each week I can adjust it depending on what you I have done in the previous week.
I have also tried unschooling and classroom (at the table) based schooling but find an overview and being very relaxed and flexible the best approach for us.
A different approach may work for you and your children. Try it all out as you have nothing to lose, read up on the different styles of teaching and the different ways of learning. Home ed is time consuming but not hard as you know your children better than anyone else.
Goodluck.
