IMO, yes, it is.
That doesn't mean you might not need child care for some of your work hrs., or that you will have big blocks of time during each day to "do school" at home. But remember, studies(and experience) have repeatedly demonstrated that children in schools get, on average, about 2 hrs max. per weekday of "on task" work/"education". The rest is crowd control. ("Waiting" as one study termed it, makes up the bulk of the school day; moving from one place/activity/subject to another, in line, waiting for someone to be disciplined, etc)
Given that, there is no reason why an hr a day/night on weekdays plus a few on weekends of "school" shouldn't be more than equal to schooling away from home. And if you don't do any structured schooling, even better; even more time that "counts" as learning
Don't discount the time they spend in care; if it is a good place , they will be unschoolong all that time. And then you can spend a few hrs one on one at some point in addition.
Right now, I do a paper route 6 days a wk(thankfully, I just got liberated from doing Sundays!
, and it works out pretty well for us. 3 hrs or so a day, home by 6 am or so(DH leaves at 6:30-7), and it helps a lot, money-wise. I sleep a bit later to be fit for parenthood(10 am or so), but we still have the whole day to be and do. But even if I worked a more conventional schedule and needed to employ some sort of child care(I would guess it would have to be from an individual, as everything is so geared towards children of "schoolage" being in school during certain hrs
it would still be do-able, easily.
It can be a challenge to meet financial needs and raise your children too, but with creativity, it can be done, even in this day and age
I decided against the night shift option, as I really value that family time in the evenings and seeing my spouse once in a while other than in passing(tho' I have known couples for whom it worked for sev. yrs at a time). Many consider me nuts to work 3-6 am, but it works better for me/us than working, say, 6-11 pm, jmo. But even if I had to work ft, I would still unschool; I would just have to work it out so I/someone else could be with my kids work hrs. Best wishes! Kimberly, mom to Forest, 10 and Lily, 2.5
