If the pre-cut's are 18" x approx. 42" you should end up with 12 - 5" blocks from each fat quarter. Flannel usually shrinks a lot so you may want to wash it before. You don't say what you are backing it with.
Sorry you feel so "obligated" to make this quilt. Remember no matter how you feel about the person receiving it, it is an example of your workmanship.
This new baby will no doubt love his or her comfy 'blankey.'
