If you can't say something nice, don't say anything at all
Choices. Life is full of them. And there are even more decisions and choices to make when you have children. What to feed them, when to introduce solid food, which kindergarten, which elementary, high school, college to send them to? As they get older the list gets more complicated: when to let them drive, what car will they be safest in, how to discipline them, how do you protect them from the cruelties of teenage years, how do you help them gain self-confidence? This lists go on and on. And all along the odyssey of parenthood the reality sets in that others will judge you for your decisions, whatever they are. If they don't conform to the judger's point of view, then suddenly you become a bad parent in their eyes.
As if parenting isn't hard enough, we have to learn to be so confident in our decisions that the comments of others don't get to or influence us. It's not easy. There are those who choose infant formula over breastfeeding and they take it on the chin for being a bad mother, or not doing the "right" thing. There are those who breastfeed and do so in public and they have to bear with the comments of others who think baring a breast to feed a child is disgusting. There are those who feel that a parent should be stricter, and those who feel a parent is too strict.
Sadly, we, as a society, are very quick to judge others without knowing what it's like to be in their position. Even more importantly, there is no one "right" way to parent. There are several "right/good" parenting protocols. It depends on everyone's unique situation and on every child.
So let's throw judgment out the window and realize that everyone is doing the best they can, whether it's choosing which feeding method is best for your family and your child, or deciding whether your teen can stay out later than his/her curfew once in a while.
