Sleep Patterns — my friend Tom has been tracking his baby’s sleeping patterns. We learnt that over the last month or so, our 5 month old baby has never gone to sleep before 10pm. We were trying to get him to go to sleep at 7 or 8pm and this was not working at all. Now it is playtime until 10 and then he just goes to sleep with no trouble, stress or crying at around 10 or 10:30. Data captured with Baby Care android app (over 500k installs) and graphed it in Python. As a father of two, this is the best ad for the quantified self I’ve seen.
