Better with You (2010)

While in labor, Mia and Casey decide that they should be married before baby Charlie comes into the world. The rush is on to make the wedding happen, as Casey and Ben dash to City Hall for the marriage license; Maddie puts herself in charge of finding an authorized person to perform the ceremony; and Vicky and Joel hurry to the hospital's gift shop to find the "something old, something new, something borrowed, something blue" items.
