Suzie’s got swim lessons, Charlie’s due for a checkup, you’re planning on yoga, and someone is supposed to keep track of it all.

Make family life easier with Three by Three Seattle’s magnetic glass dry-erase weekly planner. The 31-inch-long board mounts to any wall — we’re thinking in the kitchen or mud room — and serves as both a cheat sheet and Grand Central Station, reminding you of appointments, playdates, classes, and everyone’s comings and goings.

Available in white or green, the planner includes one dry-erase pen and two strong magnets.

Between this and child’s pose, you’ll be one mellow mom.

Available at threebythree.com, $35.
