One big (straight, gay, multi-cultural, traditional) happy family.
The Pritchett-Dunphy-Tucker clan is a wonderfully large and blended family. They give us an honest and often hilarious look into the sometimes warm, sometimes twisted, embrace of the modern family.
At the hospital Claire and Phil see the older version of their family; Mitchell and Cameron plan a day for Lily and Gloria; Manny and Jay go to a private school to look around.
