// changes to APP.js

var APP = React.createClass({

  render() {
    return (
      <div>
        <Header title={this.state.title} status={this.state.status}/>
        {/*
          The thing with React Router is that it only passes props into its children.
          This makes sense for applications with stateless components using Redux
          as the data store. But if you want to pass down state, you need to explicitly
          add the state data to the children. When I add the title property from state
          here, you can now access it through this.props.title in the child component.
        */}
        
        {React.cloneElement(this.props.children, {title: this.state.title})}
      </div>
    )
  }
});

Very astute, got me past that hurdle. Thanks.
