Snakes are not dangerous only stupid parents.
I have 3 our of the 5 worlds largest constrictors and never ever worry about my children. If I thought for a second one could come into contact with one of my kids I would not own them. My kids love snakes and they love to help me clean cages and everything but they never go into the room without me. They do not go into the room when the big snakes are being cleaned they are not allowed in when its feeding time. THey do not know what snakes eat. They love all animals and I think they are still a little to young to know what they eat. THey do not know we breed rats. My snakes are locked in enclsoures (not fishtanks) in a padlocked room. Im the only one in the house with a key.
And I wouldnt advice ever letting a snake around a childs neck.
But as long as you are a responsible parent you should never encounter a problem. I would never put my child indanger. Loosing your life to a snake would be a horrible way to go I feel so bad for the little girl in florida and couldnt imagine what that child went thru during that but she had some pretty irresponsible adults in the household with her.
Ball pythons are great snakes they get a perfect size and usually have great tempers. A perfect snake to be around children. My 5 and 2 year old love the ball pythons. But like I said as long as you take the right steps in keeping snakes like they should be kept you should be able to keep anything you desire without ever having to worry about your children.
