What to make for new baby boy? Sewing Machines Parts and Sales in Los Angeles

My sister in law is due in June with her second son (first is now 4), what are your favorite things to make for a new baby on the way? I have no children, so I’m not sure what’s most useful between all the blankets, burp cloths, etc. As far as I’m aware, she’s not having a shower (since she has some things from her first son).
