 ## Traversing
 
-Once you have made an intial selection with jQuery, you may want to traverse a little deeper into what you just selected. Traversing can be broken down into three basic parts: parents, children and sibilings. jQuery has an abundance of easy to use methods for all these parts. You will notice that each of these methods can optionaly be passed another selector or selection in order to refine your selection even more.

Traversing can be broken down into three basic parts: parents, children and sibilings. jQuery has an abundance of easy to use methods for all these parts. You will notice that each of these methods can optionaly be passed string selector and some can also take another jQuery object in order to filter your selection down. Be sure to pay attention and refer to the API docs to know what all variation of arguments you have available.

 ### Children
 
-There are only 2 methods for finding children elements from a selection: `$.fn.children` and `$.fn.find`. The difference between these methods lies in how far into the child structure the selection is made. `$.fn.children` only operates on direct child nodes, while `$.fn.find` can traverse recursively into children, and children of those children, etc.
