If your visitation times are normally the same (or similar) each time, you can use the Copy button in the Tracker to make your entries more quickly.
The Copy button takes an existing record and allows you to re-save it, making a new record.
The Copy buttons appear on the far left-side of the Tracker Month view in each row, and look like a green cross:

Clicking the Copy button will load all of the values from the selected Tracker entry, including dates and times, the list of children present, notes, etc.
Once the entry is loaded (copied) you may edit the entry as needed and click the Save this record button to save it as a new entry.
