The type of responses reflect childrens' experience. Then the answer is yes. As parents, we often see the same behavior but with different interpretations. One parent will seem oblivious to a behavior that drives another parent up the wall. If it is a behavior that children simply outgrow, the behavior will be a problem for the parent on the wall.
Parents can always ignore the behavior and try to maintain some perspective.
When a behavior is considered normal, parents should not take the behavior too seriously. If we expect problem behaviors to be temporary, they usually are. Time away leads to a better perspective. The best way to maintain perspective during any difficult phase is to get away from the child. Whether the child is 2 or 15, separation time is often a good solution.
