As simple as this may sound, KEEP A CALENDAR IN YOUR PURSE OR DIAPER BAG! When you take your kids to the dentist, and they want to schedule your kids for their next cleaning 6 MONTHS DOWN THE ROAD…pull out your purse-sized day timer and schedule away! When your kids plan a totally fun sleepover, write it in your timer…etc…you get it. It may seem old school, and you may want to be posting things on your internet calendar, which is fine. But, there is nothing like a hard copy to rely on! It’ll be the best five bucks you ever spend!
