According to a study done in 2004 by Danny Kahneman that parenting can actually decrease our happiness. This study ask women to rank their daily tasks and rate their happiness during the tasks. he tasks that involve their children actually ranked really low, being compared to vacuuming. That same study doesn't show that they are unhappy with their children. Another part of the study shows that they aren't unhappy with their children, the parents are actually happier than non-parent, and men are happier than women. It is simply the fact that the menial tasks are what make them unhappy.
