Should I Inter-link all 3 of my blogs?

I've currently got 3 seperate domain names(each being about a week old) with 3 different blogs. 2 of them are autoblogging, one I'm doing manually with my own articles(My Main One). Should I add links on all of them to link them together as affiliates of each other, or would that just cause trouble down the road if google decided to sandbox one of them/adsense ban me.

Sorry if it sounded confusing, I'm new here. Thanks for the help.

So every blog will get 2 links and it's not worth it. Get links from other domains that you don't own instead.
