As she raises two daughters while managing a yoga studio, Nashville mom Jennifer Derryberry Mann swears by Google calendars on her phone to keep everyone organized.

For Kelly Ubinger, working and raising four kids in Pittsburgh requires a huge paper wall calendar with everyone's activities recorded.

In Washington, D.C., single mom El Brown uses the digital organizing app Cozi to coordinate life with her son while running a business and pursuing a doctorate degree.

Strategies vary widely, but many parents agree that having some kind of system to manage schedules is important — especially at this time of year.

“Families with kids can wing it on lazy summer mornings,” says Cynthia Ewer, founder of OrganizedHome.com. But “back-to-school brings new organizational challenges. Adding school, extracurricular activities and sports to a family's schedule can cause chaos unless you've got a good grip on time management.”

As the school year begins, here are some suggestions on creating and improving a family system that works:

Where

Designate spots for permission slips, soccer cleats, musical instruments and more — what Ewer calls “the miscellany that will float through the household starting on the first day of school” — so you don't waste time trying to find it each day.

She suggests creating a “family launch pad” in a common area. You might place a file box on a shelf and fill it with color-coded folders (one for each child's paperwork), or tack plastic pouches to a wall, each labeled with a child's name. Donna Smallin Kuper, founder of Unclutter.com, uses Post-it Wall Pockets for this purpose.

Add hooks beneath the pouches or shelf for jackets and lunch boxes, and place labeled bins on the floor beneath each hook. Have children drop backpacks in their bin, along with items that go with them to school.

Bins and baskets are helpful for kids, said Smallin Kuper, because tossing shoes or unfolded clothing in them is much simpler — and more likely to happen — than arranging shoes in a row, or putting folded clothes in drawers.

Craft blogger Jennifer Yates has created a family “command center” using two old window screens, one for each child.

She glued clothespins onto the frames for posting papers; attached wooden hymnal holders reclaimed from church pews to hold other papers and items; and added a row of hooks.

“It hasn't helped me always turn in things on time,” Yates said, “but at least it keeps us from losing important papers. And it gives us a place to show off their work, too.”

What

The family organization app Cozi (at Cozi.com) includes a calendar function that can be shared among family members' devices and updated by kids or parents. The app also lets you record meal plans, and shopping and “to do” lists.

Similarly, Outlook, Apple and Google calendars can be customized with color-coded entries for each family member, and updated and shared among devices.

If you prefer low-tech, a large paper calendar can be color-coded for each person, and you can achieve some of the portability of a digital calendar by snapping a photo of the calendar with your phone.

Mann, the Nashville yoga teacher, combines both approaches: She uses Google calendar but also has her daughters' schedules written in colorful marker and tacked to the wall.

A digital list-maker can help you avoid making multiple, time-consuming trips to the store. Family members can update it from wherever they are. (Besides Cozi, check out the Evernote and Omnifocus apps.)

When

Ubinger goes through the kids' backpacks to retrieve papers as soon as they get home, signing permission slips and adding appointments to her calendar.

Smallin Kuper suggests getting kids involved in keeping things organized.

“You might even have just one child help you for the week with cleaning, laundry and meal prep. It makes them feel special to have that one-on-one time with you, and they are learning skills for life.”

The truly organized say weekday mornings also can be made easier by prepping lunches and snacks ahead of time. Smallin Kuper suggests taking time Sunday to prep individual baggies of cut vegetables or nuts and raisins.

Also do breakfast prep for the week ahead: Make a large pot of oatmeal, chop plenty of fruit for fast, healthy breakfast smoothies.

Embrace routine

Routine can be a powerful force to keep families on track.

For younger kids, post a “morning checklist” and “bedtime checklist” in their rooms. The morning plan might specify which sibling gets the bathroom first. The bedtime routine can include laying out clothes for the morning and making sure homework is in the backpack.

To keep homework on schedule, Smallin Kuper suggests the TimeTimer app. “It counts down the time with a red disk that makes it easy to see how much time has elapsed and how much time is left,” she says.
