"Let all things be done decently and in order" ~I Cor. 14:40
Remember the days when our young minds could retain anything and everything and we never needed to write things down. Remember when you could recall a friends phone number without looking it up...several friends numbers in fact! Those days for me were long gone after baby number one but after baby number 5 I'm lucky to remember my own phone number let alone anyone else's. The same goes for commitments and Dr. appointments, etc. In order to keep our busy family on time and where they need to be on the right day I invested in a dry erase calendar board. These range in price and size so find one that fits your families needs. I got mine at Rite Aid I think for about $10. It's magnetic and fits on the fridge right next to the phone so as I'm making appointments and agreeing to be places I can write it down immediately. I also have a small yearly calendar that is on the fridge right next to it for appointments that are in the months to come. This is not a fool proof system (remember the story of the surprise birthday party we showed up a week early for...) but it has helped me a great deal in keeping us where we need to be and when. Now I am so dependent on my dry erase calendar that I don't know how I managed without it. I keep track of the kids school things on it, church activities, appointments and engagements. I have a friend who color codes hers. I realize that people have phones they can put this stuff into but the benefit of the dry erase calendar is that it's there for everyone to see so we all know each other schedule and can just look at it and see what we have going on.
For my husbands benefit I have to add that if you are considering buying one consider whether or not you care what day of the week it starts with. Ours starts with Mon. as opposed to Sun. and it has thrown my husband for a loop.
