Welcome, glad to see you have managed your first night!! The crate traing thing, paper or no paper is your own preference. Niether is right or wrong. I don't have experience with science plan but have heard others say it isn't the best food but if its what he was on at the breeder then you will have to gradually change him over, if you choose to. I think the usual is 3 meals of good quality puppy food, whichever you choose, they should all have guidelines on them and you can adjust according to Riley's appetite and weight.
