What a cute quilt! The suggestions you have received so far are good. I am going to repeat the one about "Read the instructions on your batting. It will tell you how close you have to stitch so that things don't shift when you wash the quilt. It could be about anything, that is why you need to read. Some require 2 inches, some say up to ten.
Your little one will be lucky to have you as a mother!!
