Following a Positive Path Along the Parenting Journey

Parenting is a long journey, a little like going on a long hike through the mountains. There will be ups and downs. There will be many paths to choose from some which will ultimately lead to beauty and others which are a dead end. How do you know where to go next?
People who have been through this valley or up this mountain before can provide incredible help. When hiking through an area without a clear path, the path is often marked by small piles of rocks called cairns. You can make your parenting journey easier by looking for the cairns along the way.
For general information parenting classes and parenting books can be wonderful resources. When you are dealing with a very specific issue, the internet allows you to find people who are also dealing with that same problem. What have you found to be the most helpful for your parenting journey?
