Best way to organize nursery ?

Chellsey
FTM and overwhelmed with how much clothes I have for little man already , I'm organizing the nursery and trying to figure out the best way for clothes . 
Should I only leave out new born ? 
And then pack the rest away according to months , and pull them out as needed
 
Or 
should I leave out new born,  0-3 , and maybe 3-6? 
I just don't want clutter and want it to be as easy as possible to organize ... Personal experiences ? What's the best way to organize these mountains of clothes I have ! ?
