I don't expect my kids to do any sit down academics until they are 4, and then it might be an hour a day maximum- usually spread out over several hours. When the kids are small, we spend lots of time reading together, doing hands on learning, and just observing and discussing. We've never completely unschooled, but I definitely lean toward unstructured and child-led in the early elementary years. Works for us! My kids are presently young adult down to age 5, and we've been homeschooling for about nine years.
