This really is some good advice. Every child grows, learns, acts and deals with things differently. Being a parent takes time and a lot of patience. Mistakes will be made, but if you always show your child love, you both will prosper.
A lot of times we make parenting much harder than it should be. We overanalyze, over-reward, over-discipline, overachieve. When the reality is that effective parenting is comprised of only a few, simple things. When we focus on the core of the parent-child relationship, we can find new direction in the simplicity.
