Parental folks, talk to me about planning parental leave. How do you know how long you want to take? Does it ever make sense to save some for later? Should we all take leave at the same time or stagger it? We all have some combination of parental leave and vacation time that gives us each at least 9 paid weeks off in 2016 (the baby's due in early January, which meshes nicely with the benefits year), and have no idea what to do with it.
