I did have hand sanitizer, I just forgot to mention it. I have a little bottle of it that I keep in my purse and then just refill from the big bottle in the kitchen. The kids didn't seem to mind either, as long as they got to pet the snake.
I agree, I'm careful with my babies as well. We also take snakes to the local petsmart on the weekends and my husband and I each have a bottle in our pockets.
