48 hours seems long. I have 10 month old BP @ 350 grams, feeding him weaned rat (35 grams) every 5 days, around 7:30 pm. He's fine 24 hours later. When we move up to next size of rat I'll give him 48 hours to digest the first couple of times.
For instance I fed him Thursday night and then Friday night I left the front door of vivarium open and allowed him to 'escape'; we played a session of Hide And Seek for around 3 hours so I was picking him when he headed for places I didn't want him to go, and held him a couple of times for 15-20 minutes with no problems. He's very curious and likes to explore.
One great piece of advice I read here is: observe your snake - get to know his 'personality', and when he's comfortable being held and when he wants to be left alone.
