I seriously considered home-schooling, but by the time it even occurred to me, we were already caught in the two-income thing and my career was already well-established. Eh, we do what we can. I think every generation worries about their kids; however, today the pressures just seem so much more than even when I was a kid. More than anything I'm grateful my job allowed me to back-off the time and my husband gave his support. For so many reasons, so many people--especially single parents--have no such choices and therein lies a different kind of situation.
Your children will definitely benefit from the time you spend; they are so lucky!
