Normal Breathing? / OK Handling?

[KayLynn]

It's interesting you say that about the tongue, because others have said if they are flicking the tongue intermittently and looking around they are smelling and exploring, so Im not sure what the truth is there

Intermittent is fine, it's when it becomes constant and in rapid succession that is usually a sign to put it back. Even the most docile ball python is susceptible to over-handling. You know your snake best, but I'm just reiterating what is the general rule of thumb for new snakes and proper handling.
