The "other" child. I have married two (of course divorced the first) "middle" children, I have 3 children with a middle child, of course. I have also known several other "middle" children. They all seem to be the odd ball out of the families. Trying to find their way of living up to the expectations of the first, while trying to get the attention of the last. I hope in time my middle child will understand he doesn't need to do either, because he is original on his own. Different can be good. The expectations are given to the oldest because the parent has had longer to learn, the oldest is the learning phase of parenting, the extra attention is typically given to the youngest to avoid mistakes that could have been made with the first children. The middle child in my opinion is the perfect balance of parenting. I wish the "middle" children I have known could see that.
