Next year ds starts kindy in the mornings - most of my teaching is in the afternoons/evenings. Therefore my lovely business I have built up around my 1.5 days childcare I have is all being moved around and if it can't be done when he is at kindy or in bed then it ain't being done. I will be sad to see some of my pupils go - but I would be sadder still to have missed my son grow up.
The 24 hour thing sounds great - 13 days with 26 commutes versus 1 weekend - no question which is better for everyone. Being self employed involves less angst I find. You mention stress - but would that just be while you were there? You wouldn't spend the next 4 weeks worrying?
