Tanikit-I certainly empathize with the dilemma as we are having school issues much sooner than we expected to, although it looks as though we will be leaning towards Homeschooling because of the peculiarities of our current local, in Central Texas....
So while I have very little knowledge of the issues you face in S. Africa, I thought it might help you in your decision to know what soothed my panic attack!
I am thrilled with the idea of homeschooling A whilst she is little! In the US, I think we have a tremendous amount of pressure to focus on 'socialization', as in, if you don't send the kid to preschool you will traumatize them for life! I recently read a book basically premising that whilst a certain amount of socialization is important, the new focus on it came about as homes became dual-income families and went off to work...the 'necessity' of it and emphasis came about only as a popular means to assuage the guilt and anxiety of moms forced/ encouraged to put the kids in day care...not a popular opinion, and I am 100% sure this is not the case with many programs, especially things like Momtessori programs designed around the child!
Unfortunately, not all Montessori (or other!) programs are created equally, as in the case where we live!!!I was actually told that the toddler program here could 'not meet her needs', and the 3-6 group has such a shortage of toddlers that it is really a 5-6 group...as the things I was told go against every Momtessori principle I know, I am quite glad I will have the opportunity to keep her home...
Hence my PANIC ATTACK
As you touched on, it is one thing to consider homeschooling a LO and quite another to commit to YEARS of scary responsibility to homeschool all the way through! Serious Kudos to those able to make the decision from the beginning!
After much researching, and a chance article in a UK paper whilst visiting Hubby's family, I stumbled upon an option that allowed me to breathe again
I found several British Online Schools that cater to Expats and those residing in locals not always conducive to a great education. They have a vast number of resources, even 'online community rooms' where the kids can hang out and chat! They even have annual get-togethers for the kids and offer participation in your own local activities for credit...there are a few that we like in he UK alone, surely more in other countries. Some are pretty pricy, others pretty reasonable!
Anyway, maybe not what you are looking for, but as it helped me in the long term picture, I thought I would share!
Here is just one of our favorites:
