Im having issues with sleep. My 2 week old is currently swaddled at night, but he grunts all night and wakes himself trying to break out of it. He gets really fussy and sometimes cries because of it. It keeps both of us up at night.

He takes supervised naps throughout the day and seems to sleep better when his arms are free. He much prefers to have them close to his face.

Is it safe to put him in a armless sleep sack at 2 weeks old? If not, what should I do? FTM here and Im a little lost. :(
