I got several awesome responses and a couple that I thought were a little rude and strange lol. Nowhere did I ever say, anywhere, that I was not concerned about the children hurting the snake. The reason I did not mention this is because I KNOW kids can hurt a snake. I wasn't asking about that. I was asking if the snake can pose any real danger to the children. And I am aware that anything with teeth can bite.
The purpose of this post was because I am intending to move out of state to be with my boyfriend and his children. I wanted something to show HIM, from experienced people, any possible danger to his children, so that he can make the decision whether Sassy comes with or not. I already know my other two snakes are no-go because if they did somehow come in contact with the kids, they are big and nasty and unfortunately very beautifully colored and potentially appealing to curious hands... They have both bit me way too many times, and they already have excellent homes lined up.
Thank you so much for the helpful responses, it really means the world, and I am hoping he finds it informative and interesting. Fingers crossed,thanks again everyone!
