You can use setTimeout with respect to your code as follows,

state = {
    name: '',
    typing: false,
    typingTimeout: 0
}
changeName = (event) => {
    const self = this;

    if (self.state.typingTimeout) {
       clearTimeout(self.state.typingTimeout);
    }

    self.setState({
       name: event.target.value,
       typing: false,
       typingTimeout: setTimeout(function () {
           self.sendToParent(self.state.name);
         }, 5000)
    });
}

Also, you need to bind changeName handler function in constructor.

constructor(props) {
   super(props);
   this.changeName = this.changeName.bind(this);
}
