Yeah the last baby quilt I made was for the floor, I made it 40x60 or so and he seems to love it snuggling on the couch with his family. I was going to do it around that size, but then I thought bigger might be better? She'll probably not like the colors when she's older, unless she's like my niece who has loved purple since she knew how to name the color!, so I'll probably wind up making her another one when she's older anyway!
(Of course with the block being bigger than I thought I now need more fabric which will take a couple weeks to get here, so frustrating when I'm almost done! haha!!)
