The main screen allows a mother to track whether her baby is sleeping, awake, crying, or eating.
We want this tracker to be some sort of lever, switch, or dial that transitions between the four states. It should be clear what state the baby is in at any time. It also should be simple to switch between states (no pop up icons).
A table or visualization should give a summary for that day, with a selector to scroll through past days. This can either be a table or text, it just needs to be simple, clean, and easy to read.
At the bottom of the screen there are table view cells. These can be selected and the mother will go to another screen to edit the entry.
What to avoid
Please bare in mind, the mother will likely be looking at this late at night while very tired. As such, we do not want to bombard her with visual information and small text.
