Being still partly on maternity leave (I work 1 day a week in the lab, husband 4 days a week so Little Brother doesn’t have to start daycare until we are in the homecountry), I do most of my work as #naptimescience. This is tricky because you never know when it ends: sometimes you get a long stretch of productive time, but other times you have just laid out everything you needed to complete a task and then the baby wakes up and you have to stop. I guess kind of the same as for faculty as you never know when the next desperate grad student or disgruntled post-doc will run into your office to show you some ugly Western blog they just did. What I try to do to be productive during these unknown amounts of time is break things up in the smallest unit possible. When I have to write something I make bullet points of all the things that I have to write and then break the bullet points up into even smaller units. This way, I can take one unit at a time instead of being right in the middle of a lengthy discussion when the baby wakes up and then not know where you wanted to go next. When I do something else, like analyze data, do stats or make figures, I try to take notes of what I have been doing so that if I start again during the next bout of naptimescience I can pick up right where I have left off.
