you got to take it slow. no rushing things, no surprises, and when its enough for the day then thats it.

first thing would be to watch one from a distance, and she can decide to move closer or to keep a safe distance. basically you ask her if she wants to try and tell her how you would set it up. one idea would be that you stay with a snake in the far end of the room, and have her come in. or set up a snake in a transparent glass tank or pyrex that is closed at the top, and slowly approach it together with her.

next step, once the distance is getting smaller, would be to actually touch one, just the tail. but dont push it and dont rush it.

gradual improvement in baby steps. and work with the most peaceful and relaxed snake you have, i think thats more important than size.

i think most people that have a phobia think that it sucks to have a phobia and would rather not have it. but the problem is that overcoming a phobia is difficult work, and by its very nature its a really scary thing to do.
