Your child's hair-twirling, breath-holding, or nose-picking may drive you nuts, but most of these common kid habits tend to vanish with time -- and they may disappear sooner if you simply ignore them. However, if he's gotten into a less than stellar eating routine, don't assume he'll eventually expand his repertoire on his own.

We've got expert action plans for kids' five major eating traps.
