I'm no veterinarian but I have handled all of mine the next day if I need to move them for some reason, but I don't take them out just to hold them. I don't know if it will actually hurt them but why pester them if you don't need to.
Well, why pester them ever? I'm more asking if there is some golden rule to the 48hr thing. Do they really mind being held with a full belly? Mine tends to hide out for about 24hrs but she's back out the following night.
