How dangerous are these snakes to kids?

[JLC]

That being said, do I need to be there to supervise the kids with the snakes? I tell them that they MUST tell me when they're taking the snakes out- and so far, they always have.

There's RISK in everything we do. Allowing children to handle the snakes without you being nearby to keep a direct eye on them carries some fairly significant risks. A bite on the finger is probably not a big deal...but a bite to the face could be traumatic. Children getting hyper or distracted or childishly careless can cause serious injury to an animal without ever intending to.

How much risk you want to accept and allow is up to you. Personally, I would never let my kids handle the snakes without being there to watch and keep an eye out. But that's how ~I~ do it. No one else can (or should) dictate how you deal with your own children. All we can do is point out the risks and make recommendations.
