I doubt that PS would be less stress - gotta be up and ready to catch that bus, be around to pick them up after school, worry about what is happening all day at school (socially and academically), deal with homework/studying for tests, have decreased time to spend with the kiddos in general, have your overall schedules dictated by a school calendar.
We are leaning towards the unschooling thing here - DS is ready for K this fall but "just reading and having fun" has him FAR past a K level. Honestly, many of the things he picks out for himself are around a 3-5 grade level. He has meaningful daily interactions with DH and I - there are so many chances for incidental learning thru out the day. Incidental learning has been shown to be the "best" method of learning - it is easier to understand and to master and to retain.
We have decided to HS - but honestly it is more USing. We don't plan to change anything - continue reading, trips to the zoo and nature hikes, play dates, discovery channel programs like Life and Mythbusters are a staple around here too. LOL
I dont have any curriculum in mind. the only thing I am doing is researching and buying some math resources. And that is only cuz DS is suddenly expressing a desire to learn math (yay!!) - so I bought a Miquon book and am looking at MathUSee cuz both are hands-on/play/discovery kinda stuff.... DS spends alot of time on cosmeo.com searching his current obsession, watching their educational videos, or playing the great "brain games" there.
I don't think our lack of formal learning has been harmful in any way to DS or will be int he future - in fact I think it is the opposite. By allowing him to learn things at his own pace and in his own way - he enjoys it and retains it! he is loving learning and is creating his own work ethic when it comes to learning. I think it also prompts him to think for himself and to think outside the box (compared to being spoon fed info and regurgitating it) - he is so proud of himself when he figures something out, and once it "clicks" he has got it for good.
He has this amazing thirst for knowledge - he devours new stuff. He finds a new topic and pursues it to exhaustion (and often mastery - or as much mastery as he is ready for) - with no prompting or coaching from us, just meaningful interactions and play. Most PS kids don't have this thirst for knowledge - but instead view learning as a tedious, unstimulating chore.
As far as DS being behind now (or later) - He is actually quite advanced for his age in some areas. He reads chapter books and enjoys reading DH's A&P text books LOL Thanks to teh World Atlas map turned backwards, he learns about geography in the shower (per his request!) and has a better understanding of world geo than I do! Other areas, like math, he has had NO interest in and a formal curriculum and "teaching" would have been met with resistance - cuz he wasn't ready for it yet. Now apparently he is ready, so we are playing more mathy games (cards, board games, etc) and looking into manipulative based learning programs to loosely use to discover math concepts.
I like to call it child led learning - and it works well for us. It is fun, flexible, not stressful at all (esepcially once you give up the ideas of "he should be doing this" or "he should know this"). It just feels "right" It is so awesome to see DS so eager to learn. Plus the flexiblity is nice - no worries if we spend a whole day (or week) reading books, playing dinosaurs and swimming. I know that in all that "play" time, he was learning and practicing things too. I honestly think he gets more from this style of learning than he would from workbooks and flashcards.
even the "experts" agree - kids learn best thru play
Just follow your gut - if the last month feels "right" then it probably is. Maybe that will change in a year or ten from now - but if it ain't broke now, don't fix it! lol Trust your gut cuz momma's instinct is so right on!
