As others have said, wait for iOS 6.1.3 to release, update, and then give it your sis.

Although, if the evasi0n team finds a way to jailbreak 6.1.3 you're going to be out of luck (doubtful they'll want to burn the other previously mentioned exploit for a 6.x.x jailbreak)
 
Why give them something that you are worrying about him breaking? Perhaps give him a stuffed animal or something that isn't expensive.
 
I know that if they keep it up to date that is some bit of a way since the JBs take a little bit to come out but is there a way to make it not be able at all?

The reason I want to do this is I am giving my sister an iPad and her husband is mildly computer literate and likes to screw things up. Happened with her nook tablet, he rooted it and bricked it. Bricked 2 of her phones, etc, etc. Anyways, I want to make it so he cant jailbreak it and screw it up. She wouldnt even know how to take advantage of any of the jailbreak stuff anyways so it wont help her.

Is there a way to make this happen?

Dont give her/him an ipad! Easy fix
