I've read that most people find it difficult to remember events prior to 2 - 4 years of age. It's called childhood amnesia. It's very common. You can't blame yourself for your childhood behavior. It's not that uncommon for children to be a handful. My nephew was a nightmare. A typical example is if he saw a stranger he would kick them in the chin. Now, honestly he's the nicest person I know. He's now in his late 20s.
