Answer
You didn't mention the age of the dog or where you got it from, so it's tough to give you clear direction, but the overall idea of anything is the same.  Training . . . and lots of it.  Until that happens, keep your son away from her and supervise all interactions just to be careful.  Chances are, the Sibe simply doesn't have any boundaries yet, and you will have to help teach her those boundaries.  Also, get your wife involved in the obedience training and make sure your are doing everything to help establish that you, your wife and your son are in charge of things and set the rules.  The dog will eventually figure that out and should be less aggressive.

If you don't have experience dealing with stubborn and potentially aggressive dogs, I strongly suggest you find a professional trainer immediately.  Some of the tricks are difficult to explain over email or the internet, but can easily be shown in person and applied.  And they also can fix problems in days if not hours.  But the most important piece of advice I can give is lots of obedience training (sits, downs, stays, heels, etc.)  Make the dog work for every meal, pet, play time, etc.  And work can be a sit, a stay, a down, just some command to help establish the hierarchy.  Also, it needs to be consistent from you, your wife (and eventually, your son as you get things in more control).

Good luck and if you can provide some more specific info on the dog's age, background, etc., I might be able to help a little more.
