I Want to Be a Good Parent

I want to be a good parent. I guess kind of don't know how to handle situations sometimes. Nobody ever told me that parenting would be this hard, and I just want to make sure that I am doing the right thing for myself. I have always wondered if I would ever enjoy having kids, and now that I do, I enjoy it. But I just feel like maybe I am not giving it my best shot because I am afraid that I might do something wrong that will change my child forever. I know that my kid is like any normal kid. He throws tantrums, but he has his good days. I just want to look at the fact that I am going to be a parent for a long time, so I better take some online parenting classes to make sure I am doing it right. I don't want to ruin his life because I am incapable!
