My very favorite baby sweater to knit is the BSJ. I knit this one on size 5 needles, using Bernat Baby Sport yarn. I added a simple collar to the sweater. I shopped my button stash and found 5 round ball buttons perfect for this sweater. I Love it when I can find buttons from my stash to fit a project! The baby isn't due until December, so I will probably knit a hat and booties to go with the sweater.
