There are definite pros and cons to both set ups. I find my WAH days have much less shape to them than my in-office days. I start earlier, finish later but generally have blocks here and there where I’m taking care of other commitments (be it a dr’s appointment or school volunteer commitment, etc.).

I’ve been splitting my week this way since my youngest was three. Barring a child being home sick now and then, I have never ever used it as a substitute for child care. It’s untenable for the employee and unacceptable to an employer. Obviously, it’s a different set of rules if you’re self-employed.
