Two, a pigeon pair!
As such, was able to afford Private Schooling Grades V to XII, inclusive, for both.
As first child went to Grade V, second child started at local State School, Grade I.
It wasn't for four years' until we had to deal with two lots of PS fees, but in those four years, saved like crazy for the 'yearly double' until first child finished Grade XII, then back to one.
All was planned that way, & it worked out well.
Both, now adults, are very well qualified in their respective Professional careers.
