This type of behavior is typical hatchling responses to obstacles in their space. Human babies cry and throw tantrums when they are hungry, upset, scared or otherwise unhappy. Baby snakes will hiss and huff and puff including striking out to bite when they are frightened and stressed. Definitely everything that is posted here is all factual and inclusive of the points that will help you and your daughter begin to understand and enjoy your baby ball python more. You will really need to reconsider such a large enclosure for now. Baby ball pythons do much better in 6 quart tubs. If you want to use a glass enclosure a 5 gallon is a better temporary housing that will help to expedite his adjustment and well being. Congrats and welcome to baby ball python care 101.
