After a little searching I found this thread on another forum, which was very helpful.

My son absolutely adores our bp and is very gentle with her, but has absolutely no fear of her. It's a good thing she's so mellow, because he's pretty constantly in her face. Let's just say she's not exactly head shy anymore.
If you check my sig, you'll see from my blog that my son is extremely allergy prone. If anyone were likely to react to a bite it would be him. We'll probably have to skip the hoggy for a sand boa. Too bad, since they are adorable little spuds!
Thanks everyone for the help! We'll probably get the new baby in January or February, so I'll post pics then.
