First off let me say Welcome and Congratulations on the new baby!!!! :D :D :D
You could go to quilter's cache and just browse through all of the blocks until one yells out "pick me"
Most young people pick a theme for their little ones...my daughters all did, so you may look at fabric within the theme and get an inspiration there too.
You could try googling baby quilts, and take a look there at what others have done, you have seen many on the board, you can do a search here on baby quilts also to refresh your memory.
