once bitten twice shy

Here is a bite that I got yesterday on my arm...Gross, isn't it? I was hoping it would look a little better today, but it looks worse!

What horrible little creature would do such a thing you ask?

Yes, that would be my son Brayden! He has bitten me 3 times now...this one being the worst. I don't know what to do...the sad part is, I think he is doing it out of affection, cause that's how he "kisses" his stuffed monkey. Either that or he is practicing for the sequel to Twilight!
