Hi,
He sounds like he is doing all the normal things that a 7 week old baby does. Do you have a baby sling/ I recommend one like ABA's Simplicity sling - holds them close to you and securely. (and inexpensive) They are gold. It may take a little while to "get the hang of it" but worn correctly it won't be heavy on your back. You won't hear a peep out of him. At night, have him close to you - in your bed is great.
