2.5 week old

I have a 2.5 week old who is mostly a chill baby. When it’s bed time though, I can’t seem to put him down and it takes me a couple of hours to get him to settle. Could I be creating a habit of him always being on me? I hold him a lot but he does take some naps on his bassinet too… he’s just not great at putting himself to sleep and typically needs the boob. Any advice? He hates to be swaddled so I leave his arms out…
