Thank you for your concern. I ended up on this group because my then 7 yr old wanted a snake. We adopted an adult corn soon after.
They really are wonderful pets. I was nervous, too and did a lot of research and made sure my daughter had as well. A few months ago, we adopted our 2nd snake, a ball python.
I will also add that my daughter has learned SO much from her snakes. Not just in the reading and research about them specifically, but about animals in general, about research, about habitat preservation in the wild, and much more. She's always loved animals, loved nature shows and the like, but having her own animals has made it far more real to her. The snakes have given far more than they've taken.
