Because we were supplementing heavily at home, he also had less down time, which was a whole other can of worms.
I can relate to that particular pang on my conscience.
One of my major dilemmas is the push/pull of whether to keep my DD stimulated and learning in key areas (language arts and Maths) and reduce unstructured time as a result or whether to cut back on the after schooling to allow more unstructured time.
And that doesn't even get into Music lessons, an area where she has natural ability but one in which she must take lessons to get better - further reducing UT...
Life as a natural over thinker/worrier sucks at times LOL
