Don't be too overly concerned. Different BPs have different tolerances. Some you could carry around with you all day long and they'd still behave (read: eat) normally. Some get upset and will refuse a meal if you've done something silly like move them for a couple of seconds while cleaning up after them the day before. As long as he's eating well, there's really no reason to not enjoy interacting with your new arrival! Just keep in mind that the feeling's not exactly mutual. ;)
