Cheaper by the Dozen 2 (2005) Review
This sequel to the 2003 release takes us back to the Baker clan, but this time things have changed a bit. Tom Baker (Steve Martin) is presumably still at a small college, while wife Kate Baker (Bonnie Hunt) has still only written the one book (according to comments in the movie) - yet they are still in the massive house in the city that they purchased, so you have to wonder how they make ends meet.
Nonetheless, life moves on, and the third eldest Baker, Lorraine (Hillary Duff) is graduating high school. This is a time of change for Tom, and change isn't always good.
