If you have a kid or kids or plan to, this article is worth bookmarking. Here are the first three items at the link:

1. Self-sufficiency. This one tip could simplify your life greatly, over time. However, it will make things more complicated in the short term. The idea is to teach your kids to do things for themselves as they get older and more capable. Teaching them to do something themselves instead of just doing it yourself takes time and can be a little frustrating at first, but it will pay off for years to come. My kids, for example, can make themselves breakfast, shower and dress themselves, brush their teeth, and generally get themselves ready in the morning with only minimal prompting from us. They can clean their rooms, wash dishes, sweep, mop, dust, wash the car. The older ones can cook basic dishes and babysit the younger ones. This type of self-sufficiency has saved my wife and me tons of time and trouble over the years.
2. One calendar. If you have more than one kid, you might have a lot of activities going on that you need to track, from school events such as Christmas performances and parent-teacher conferences to extracurricular activities such as soccer practice, dance classes, or Spring concerts. Organize your life with a simple calendar (I use Google Calendar) and enter all activities and appointments on this one calendar, from kids’ stuff to your own goings on. When they hand you papers from school, or soccer schedules, immediately enter everything onto the calendar. Then a quick glance at the calendar each day will help you plan your day.
3. Toy bins. It’s an inevitable fact of life that kids have lots of toys, and that they will be everywhere. You will drive yourself crazy if you try to manage them with dictator-like ruthlessness. Instead, let kids play, but have lots of bins where they can toss the toys inside when they’re done. Then cleaning up is a cinch — they just toss everything on the floor into the bins, and move on to making their next mess. You can have designated bins for certain toys (this one’s for Legos, this one’s for stuffed animals, this one’s for cars), and also have some general-purpose bins for things that don’t fit anywhere else. Don’t be too strict about them — the whole purpose is to make things simpler.
