There's never been such an incident, so there's nothing documented.
I imagine that you wouldn't want to subject a newborn to a 3000 gram python's accidental feeding bite, but that really isn't going to happen, is it? lol
Put a latch and padlock on the door to the snake room. You'll need one anyhow, to keep the baby out once it's a toddler. If you get into that habit now, you'll be unlikely to forget it when the little one is wandering around. You, the baby (and the snakes) can rest safely.
I'm a parent as well, and I was more concerned about what the baby would do to the snakes than what the snakes would do to the baby--the latter have quite a grip on them.![]()
