Hi, I would suggest that you have your dad wait a while before attempting to pick him up. Your idea to keep Bright in the cage for 1-2 days is wise. But you can take him out for some supervised play time with you every day for about a week once you have bunny-proofed your house. It’s good to start only in the room his cage is in. He can come out with you sitting on the floor (read, or play on a tablet in your hand) just ignoring him. Keep an eye on him, though, but let him walk out by himself. He’ll be cautiously ready to explore that room. Bunny proof it first. Then let him come to you. When he does, you can hide a treat for him to find in your hand or a pocket, or just offer it to him. Do this one room at a time, and don’t be dismayed if he shows little interest in exploring other rooms for a while. Your dad can also sit with you, so Bright can sniff and explore him as well.

A bunny wants to be secure in their habitat, and their cage is home and safe, not a prison. So he will explore in ever-widening circles as he gets to know the new house and people. If your Dad helps with feeding meals and daily play time, it will only be another couple of weeks before you can work on picking Bright up. Bunnies don’t like to be held, and hands spread wide coming down from above are scary (look like claws) so neither of you want to approach him that way, especially at first.
