DISCLAIMER : the following snippet can be refined, but it is just to tell you the general idea.
http://jsfiddle.net/Lox5w8ge/1/
First of all id's should be unique, so never duplicate them! I removed the child_div id and made it a class. Since you do include jQuery I decided to use it and use the powers it gives to add some events to the buttons and to select the correct elements.
$('#create_button').click(function() {
var html = $('.child_div:first').parent().html();
$(html).insertBefore(this);
});
$(document).on("click", ".deleteButton", function() {
$(this).closest('.child_div').remove();
});
I first get the html from the first child_div I find and insert it before the button used to add the div.
To remove the child_div again I first added a button to it with a specific class deleteButton with jquery I added a click event that when clicked on this type of button will find the child_div containing this button and then remove it.

By JQuery
var x = 1;
var field ='<div><input type="text" name="field_name[]" value="" /><a href="javascript:void(0);" class="remove_button" title="Add field"><button class=" btn btn-danger" style=" margin:5px;">Remove This</button></a></div>'
$(".add_button").click(function(){
if(x < 10){
$(".input_field_wrapper").append(field);
x++;
}else{
alert("max ten field allowed");
}
});
$(".input_field_wrapper").on("click" ,".remove_button" , function(){
$(this).parent("div").remove();
x--;
});
