I would leave in all the Seuss fabrics and take out the green and red and put in substitute them with the yellow so there is more continuity of color. Busy is good for a baby. If you want the white sashing that's fine but I like the Seuss more. Put something soft and cuddle on the back like a fleece and it will be her favorite. Babies respond to colors and texture. Remember this is a baby quilt not a quilt show quilt. It's darling!
