My buddy has raised 3 kids with snakes, including large boids and venomous. The snake room/building is locked, cages are locked and they haven't died yet. The children are all quite comfortable with the snakes and handle all of them (except the venomous of course). Wash your hands. If you tend to drape your snakes around your neck, change your shirt and make sure your skin is clean so that if you hold the baby up on your shoulder their mouth won't be where the snake had been. It will be fine.
