I handle all my snakes as often as I can, usually that means daily except if they've just eaten (and for 2 days after). Once the snake is settled in and taken 2 meals in a row for you (that's the rule I go with for any snake), then you can slowly introduce handling to the snake, say 10 minutes every other day for about a week or two, then slowly make the sessions longer and more frequent.

After that, when they're used to be handling, you can handle as long and as often as you want, except the 48 hours following a feeding.
