If parenthood is all about juggling, then working parenthood is about juggling 10 things at once. If you try to keep your work, your kids, and your own schedule going on one calendar, chances are it is pretty packed. It also often means that your colleagues get notices for your kids' doctor's appointments because you were just trying to block out the time. With UpTo — Social Calendar (free), you can share events with whomever you want while still blocking time on your calendar so others know you're out. Which means your colleagues can receive a notice that you need to leave early on Thursday, but they don't need to know it is for the school play.
