Now wait OP, the first time you said bite and constrict, the second time you just said she started to constrict. Did she bite you the 2nd time?
Even young ball pythons can squeeze you very hard if they feel insecure. If I'm holding mine wrong he wraps his whole body around my arm or whatever he can grab and squeezes me until I take him off and support his whole body.
You have to remember, these are terrestrial snakes so they like to be supported and feel safe, and as babies they are even more afraid and clingy.
If the snake is a hatchling, be feeding every 5-7 days, I prefer 5 for very young, 6 for my 5 month old, and 7 for almost adults to adults.
I would suggest one small adult mouse every 5 days if it is a small hatchling.
If not a hatchling one or two mice, or a small-medium rat every 7 days if you are talking about a larger snake.
