Unless your daughter is capable of taking care of the snake on her own I would not buy any snake. All too often a child loses interest in a new pet and the responsibility of caring for the animal falls on the parents. Your wife has said that she is not interested in feeding the snake and since that's pretty important that means you will most likely be the one who has to take care of the animal. Pets are hard enough to take care of when you love them. If this is going to be a burden and not a love then the animal is the one who will suffer. Owning a snake without getting bit is like, owning a dog without your stuff shoes getting chewed, or owning a cat without getting your furniture scratched. Its certainly possible that you can get your new snake and never get bit, but you should not go into snake husbandry with that expectation. A ball python bite is nothing. I am twice as afraid of getting a flu shot, paper cut, or stubbing my toe.
