The prey size sounds a bit too small to me. Prey size should be same size to a maximum of 1.5 of the girth size of your baby.
Besides hunger there are many other reasons for why a BP could strike/bite. Here are a few:
Handling prey items or petting the family dog/cat without washing hands prior to reaching into the snake's enclosure.
Startling the sleeping snake by lifting it up without first making sure that it is aware of its keeper's presence.
Using the same routine to handle the snake as is being used to feed the snake. - If you are feeding in the enclosure, try feeding in a separate feeding box. Some (not all) develop what's called cage aggression when fed in the enclosure. I've never fooled around with it and can't say whether that really is an issue, since all my snakes have always been fed in separate feeding boxes.
Infrequent handling - You mentioned that you leave the baby alone for three days after feeding. If you are feeding it only small fuzzies, it certainly wouldn't take it that long to digest them. Two of my juvies are still on rat pups. It takes them two days to digest those and then they are out and about and ready to be handled again.
My suggestion, if it's indeed the meal size: Up the meal size, feed in a separate container and start from scratch regarding handling. Handle him routinely at the same time every day (give him two days of rest after meals). Use gloves at first and be calm and persistent when removing him from the enclosure. Keep him out for just a minute or two and put him back in. Increase that time every day until you feel comfortable enough to remove one glove. Touch him (don't pet him) with your bare hand. Once he doesn't jump anymore when touched with your bare hand you are safe to remove the other glove.
Remember, that snakes do not have the ability to memorize for a very long time. Once your BP knows that he's safe with you continue handling him regulary. He'll recognize your smell and the feel of your hands and will associate safety with it and will stay sociable.
"i have no problem feeding him whatever or doing whatever it takes to make him happy and less aggressive" - Love your attitude!
Best of luck!
