Things like this make me angry and that parents let it happen. My very good friend has a two year old and she has played with each of my snakes big to small. Good for their socialization as well. She understand to touch them softly on their back, no touching their head and to moves slow around their face. She will be great as she gets older. I found out now she makes play doh snakes at home and names after my snakes. She even gets the sizes right. She can distinguish between baby and juvenile.
People need to educate themselves about any animal they bring into the home.
