First world problem, I know, but I'd like a better method to track "irregular" nanny hours than just jotting them down on a piece of paper. Something on my phone would be ideal, for those days when the nanny stays 30 minutes later than usual, etc., so I can track the time and not be scrambling every two weeks to remember which days were different from our typical routine. Any suggestions?
