Imagine a bunch of parents using a free/relatively inexpensive application, tracking feeding schedules, sleep, food intake, play etc. and then ranking each day as a thumbs up/down.
Taking that data, properly anonymizing it and then comparing it across babies with similar characteristics (location, age, siblings etc.) you could suggest a daily schedule (with alerts) that would trend closer to a thumbs up.
Started with a prototype, but it never amounted to much. I just imagine the collective value of some of the data managed by these applications and the potential to ease the extremely challenging (but rewarding!) experience of being a parent.
