Congrats, how exciting! I agree with the above comments in that a lot of it can be the fabric that you choose that makes it a baby quilt. Depending on how easy you're wanting there are also a lot of adorable panels out there that make for a quick quilt but not much or any work on your end. That being said here are some links to some cute or easy patterns.
