The kids and I watched this together. I know I'm not supposed to, but I think I actually liked this better than the first one. The first Cheaper by the Dozen (with Steve Martin and Bonnie Hunt; not the old one) seemed to have even more ridiculously chaotic moments than the second. Though I admit that Steve Martin was physically sillier in this one. Okay, maybe I can't defend my preference for the second one very well. It's true that these funny depictions of large families do no service to large families. But this one had two large families, one with twelve kids, one with eight, and one of the points of the movie is the nearly opposite parenting styles, and how both families turn out good kids (although kids from both families get into trouble).
Also, I liked that the trophy wife of the "competing" family turns out to be pretty cool. And that the kids are all nice and like each other. And that it's just the dads who are lame and overly competitive. Okay, I do find the dad-is-stupider-than-mom characterization annoying and harmful (Everybody Loves Raymond and just about every other sitcom around, for example), but it could so easily have leaked over into the kids in this movie, and it didn't.
I always criticize birth scenes in movies, and this one's no exception. But the criticisms are minor: I don't think the family has to wear scrubs in the delivery room nowadays (though I suppose it's possible in a small resort town hospital), and the labor went pretty fast for a first-time mom. But who cares about that? I'm writing it, but I don't think I care that much anymore.
