I agree with this wholeheartedly! The WTM recommendations for K are actually simple if you live teaching. My dd helps me cook, bake, clean, etc., and normally does some sort of "school" each day, but we don't do everything daily. We read a lot, but other than that, things are mostly taken on a how ti comes basis. For example, today we were baking cookies, so we learned about measuring. When we speaks and uses improper grammar or pronunciation, I simply correct her. Her science for now is growing some plants with her daddy, and reading books. and whatever daily science she may encounter such as insects, birds, etc.
We don't want to overwhelm her or become one of those parents that are pushing too hard. School will get serious soon enough!
When I started 11 years ago, I ordered every catalog I could get my hands on and started looking for online reviews and talking to people, just like you are. I am sure you will make great choices for your babies! :)
