S.,
My boys (now 6 & 8) were a little younger than yours when I came upon the Flylady website. I LOVED IT! Now, let me tell you that you have to take what she says with a grain of salt. I found it almost impossible to keep up with her schedule with two very young boys constantly making a mess behind me. It also helped give me a routine when I needed one because I seemed to have all the time in the world but nothing ever got done.
There were some aspects of it that I liked and still do. I found that her 27 fling boogies (where you tackle a room or a closet getting rid of 27 things - either to where they belong, to the trash, or good will) is very therapeutic for me. When I get to feeling down I straighten out a cupboard. In fact my best friend and I are also saying ," I'm doing a flylady boogie!" I also LOVED her notebook idea. So now I have a notebook on my table with dividers that has all the info I use on a regular basis - emergency info, membership cards to places we do not go to frequently, addresses & phone numbers along with a folder with cards, envelopes & stamps, a receipts folder (this is very handy at Xmas time), and a few other sections. This way my papers all together at my fingertips. I still do a weekly homeblessing, but now my boys are old enough to help so I get a lot more done in 1 hour than I used to. I try to break up the laundry so I am tackling one load a day, not 8 on a Saturday. And the kitchen is neat & tidy when I go to bed at night (probably 27 out of 30 nights a month - sometimes you just gotta go to bed).
As for all the emails, I think you can sign up to get the digest and just get one email a day that has all the info.
Enjoy!
