When Dan wants to upload the adorable image of a paint covered Chuck, Dan would click the Events button, click the "Add Children" button and type and select Chuck's account. He would then select the "Text" text box and type up his comment. At the end, Dan would click the "Add Photo" button, select the desired photo, and click the "SHARE" button.
Again, 
the new event will pop-up on Paul and Patricia's ChildFeed feed, so they will see the unread story. Patricia will see a thumbnail of the photo and the first few lines of the comment of the story. Patricia would then click the story in order to trigger an info box overlay with a larger version of the image and the full additional text.
When the children are eating their meals Dan will click the "Food" button from the main menu and begin entering each child's meal. To do so, Dan will either add a new meal or select one of the existing meals and then click on each of the children who ate the selected meal(s). After every child selection, the child's displayed meal will be updated to selected meal and Dan would then have to select the amount that the selected child has eaten.
