Why can not work treatment via children?

Here is the code https://jsfiddle.net/5snj8a75/
Not working fadeIn and fadeOut though if to be more exact - nothing works.
Derail, all the way up to $(this).children('div')works, and even $(this).children('div') returns an object.
What could be the problem?

and why did he then children? if it's siblings. tobish are you doing on hover .year - and inside it there is nothing. just near there .info, next. and not inside .year

you need something like $(this).parent().children('div').fadeIn();
