spider acting weird.

okay, so... i was holding my 1 1/2 month old spider the other day and he's usually always in a ball when i hold him... but this time he kept lifting his head and neck up really high like he was looking straight at the ceiling and then falling over... he did it a couple times and then i noticed that his stomache was kinda puffed up like it had air in it or something from his cloaca to about 2 inches up from there, it seems to be gone now and i havnt really held him since... he also has a really bad head wabble too. are any of these things something i should worry about???

To worry about? I would say no. Your spider is exibiting alittle bit of the spinning trait. Some do it to a greater degree than others. As long as you little guy is eating and growing like a Ball Python then you've got nothing to worry about its just a trait that spiders exibit. No big deal in your case.
