corns are nice, small, pretty but they are colubrids.
They like to move. Yes, the biting will go away with handeling,
even baby boas bite more often, a little baby snake doesn't
have much in the way of defense except to bite and when a big
hand is picking it up, it's not sure if it will be eatten or not.
So, yes the biting will stop but the corns are active movers,
my b/f was holding my adult corn on the couch, watching tv,
he looked down and half the snake was into the couch cushions,
so needless to say I got the snake out and destroyed a couch.
For a child, deff supervise any interaction with any snake,
both for the child's safety and more so for the snake's.
I think a rosy or sand boa would also be a good choice, they
stay small and are pretty, and ball pythons are good choice
too, as already stated they are shy at first, I usualy held
my ball for about 10 min, then he would eventually start to
come out of the 'ball shape' and start to explore.
Now, I like corns, so that is a good choice too, I just
wanted to warn you about how active and fast they can be.



(oh and the albino boa for less than $200... did it look
