DadHack: Sippy Coffee

As part of a daily ritual, before we go to the park, I find us going to the local coffeebux every other morning. Now that the kid can hold up a sippy cup, she really wants to hold everything, including her bottle. Problem is, it's not wide enough for her yet. Her bottle has no handles. BUT, add an empty coffee cup to the equation, AND: Volia! Someone is part of the group.
