problems inheriting from a c++ template class

problems inheriting from a c++ template class

So I'm trying to work out how inheritance works when templates are in the
mix. Most compilers really don't seem to have this figured out yet, so I'm
having a little syntax difficulty. All the weird includes in SkipNode.h
are from trying to get eclipse to stop yelling at me. I'm getting a syntax
error when trying to declare the constructor in SkipNode.h, so any help
here would be useful.
Here is node.h
#ifndef NODE_H_
#define NODE_H_
template<class T>
class Node
{
public:
Node(Node<T>* next, Node<T>* prev, T item);
virtual ~Node();
Node* getPrev() { return prev;};
Node* getNext() { return next;};
Node* getItem() { return item;};
void setItem(T item){Node<T>::item = item;};
void setNext(Node* next){Node<T>::next = next;};
void setPrev(Node* prev){Node<T>::prev = prev;};
private:
Node* next;
Node* prev;
T item;
};
Here is SkipNode.h, where skipnode inherits from Node.
#include "Node.h"
#include "Node.cpp"
#include "SkipNode.h"
#include "SkipNode.cpp"
template <class T>
class SkipNode: public Node
{
public:
SkipNode(Node<T>* next, Node<T>* prev, Node<T>* child, T item) :
Node(next, prev, item);
virtual ~SkipNode();
Node* getChild(){return child;};
void setChild(Node* child){SkipNode::child = child;};
private:
Node *child;
};
