Stick on thermometers are pretty much useless as they are very inaccurate. Get a temp gun or at least some digital thermometers with a probe. Also, ball pythons are not arboreal snakes (as much as the babies seem to wish they were). So providing him with an adequate 90 degree hot spot on the GROUND is necessary. This is also where you should be measuring your temps and not up by the light.

I agree with what the others have posted here. Smaller enclosure, nice and snug hides on both hot and cool side.

I would refrain from handling until he eats at least twice. Only offer food once every 5 days at most.
