Small children do not understand their emotions. It is adults responsibility to monitor all toddlers from newborn to five. Children in that age group should never be un-monitored by adults.

My two-year older brother developed jealousy of me when I was born. This is a common phenomenon. Parents should know about this and deal with it but most do not. My Mom's parenting skills actually promoted my Brother's jealousy and eventual hatred of me. She told both of us when we were toddlers that it was normal for older brothers to "pick-on" their younger brothers. My brother developed an obsession with making me cry. I had no peace in my own home growing up.

But here is another case of parents not doing a simple thing to help their children. All I needed was one of my parents to talk to me about this relationship and help me remove my emotions from it. In my case it was the emotional pain that my brother caused me not the degree of physical abuse that caused me to have mental health problems. I was being abused by a family member that I loved so it caused me extreme emotional pain. I could not get out of the situation and I had no one in my family that had any common sense that I was being damaged psychologically by my brother.

Toddlers can be mean to other toddlers but they do not really understand those emotions and it is the adults responsibility to deal with these things when they come up. You, as a small child, should not have been left alone. Then this situation would not have occurred.
