Babies do not care. Make any quilt that brings you pleasure. As the baby gets older they will be attracted to any of the shapes, colors, figures, prints and so on in their quilt. An I spy is just as appropriate as a floral or race cars or tractors or animals or colors or pastels or......you get the idea. Adults are the ones who chose pink/blue or pastels/bold for babies. Babies just like to be warm and to be snuggled. Have fun making your quilts and giving them away.
