I would agree with the "no handling for 48 hours after feeding" rule, at least for now while your snake is young and not yet familiar with you. I followed that rule fairly strictly for the first couple of months with my BPs. Later on, you may be able to allow for just 24hrs, because your snake will be used to you and recognize you're not a threat, and you will also know your snake better and be able to read his body language. I also do distinguish between routine maintenance handling - i.e. moving or picking him up briefly because it's necessary to check a temperature or clean up a spot of pee/poop - and recreational handling, i.e. bringing him out to play with him for an extended period of time.
