My 2 worst parenting habits are not being consistent. Kids never know if they are going to get it for something this time..but might get away with it next time. The other is procrastination.  For example, I have one that has been asking for a couple months to go to the library. We almost never do this, and it is something that we do enjoy. If I would just take the hour to go, it would make both of us  for the day.
