Welcome to BPNet and congrats on your purchase of a ball python.

Kids and snakes present some interesting situations. We have 4 kids of our own from age 6 to age 20 (really not a kid anymore lol). Each age group has it's own good and bad points when it comes to interacting with snakes. With younger kids there tends to be more issues with quick movement and squishing/gripping too tight. Just encourage your daughter to sit quietly with you supervising as the snake moves around on her lap. I'd avoid handling the day of feeding as the snake will be ready to eat and for 2 days afterwards. Also avoid handling when the snake is in a shed cycle (there's an excellent sticky on the shedding process here). Lastly, remember these are nocturnal snakes so sometimes taking them out during the daytime can trigger them to be grouchy as they were resting.

They are not major biters but of course can bite. If it helps you, we have 26 snakes, I've been bitten once, none of the kids have ever been bitten. Learn to know the snake and when it's extremely tense and just react accordingly. Make handling sessions short, calm and quiet. Don't hover over a snake, especially a young one, that makes you come across as a predator.

I think you'll do fine and sound like you're going to be a great snake family. She'll learn to enjoy and respect this new pet. My kids really love all our snakes and depending on age and ability, do quite a bit of work with them and the rat colony we have to feed them.
