I don't know if you should be concerned.  I think it might just be something all kids go through until they learn not to.  And I don't know if all of the things people say work or not.  I do know what worked for us.  When Butterfly was 15 months old and I was 8 1/2 months pregnant, she bit me on the belly and I screamed in pain.  That reaction from me upset her so bad that she never bit anyone again, not even when her little sister started biting her.  So, maybe you could exaggerate your reaction to the pain.  It is worth a try. 

Definitely worth a try, I will let you know the response I get.  Last night he began pushing me with his arms, not quite hitting, but a tiny temper tantrum for sure.

I wouldn't be worried at all!  I  know that sounds funny, but it really is a stage a lot of kids go through.  I have worked in child care for years, and biting can occur for different reasons.  Frustration with not being able to talk as much as they would like to...teething...having seen someone else do it and get a reaction... wanting attention...etc...  The overacting suggested by Tricia can definitely work on a sensitive child.  If that doesn't work, a firm NO BITING! and walking away can also do the trick.  Overall, don't worry, it will pass.  Not my favorite stage, but it always passes.  : )

Nip it in the bud.  Look at him and make it really clear that he is not to bite SKIN.  I had a little kid bite my daughter when she was little and the mother just blew it off like it was no big deal even though he drew blood.  So this subject is a biggie for me.  Teach him not to bite people early or the next thing you know, he will be biting someone else's child and I can tell by your concern that you are not the "blow it off" kind of lady.
