I thought this would be a good post for moms to exchange organizational tips! Here is what I do:
I have 6 weeks old triplets and 4 and 2 year old girls, so my life is basically scheduled hour-by-hour. Naps, meals, etc, it's all on there. We have lots of different people working with our family and I find it's the best way for everyone to stay on the same page and to make sure nobody forgets who is doing what and when. For example, it says who is picking up the girls from school that day (sometimes the nannies, sometimes me), who will prepare meals and when, etc.
Every Sunday I pick out an outfit for each day of the week for my oldest two. I find that it is much easier to grab an outfit off the hanger than to pick something out, worry if it's wrinkely, etc.
Each Sunday I also plan dinners for the week, as well as have a general idea of breakfast, lunch, and snacks. I have dinners made and frozen or the recipies set out so myself or a helper can prepare it quickly.
Right now I have changing stations throughout the entire house (living room, basement, and each child's bedroom). Each night the older girls help me go around and re-fill the diapers and wipes.
We keep diaper bags in the laundry room (not that we've ever ventured out with the babies yet, but I've done this in the past too). That way when you're folding laundry you can throw in onesies, socks, mittens, hats, and recieving blankets.
