The way I figure out what fabric to use is to lay the fabrics together and back off about 6 to 10 feet. Sometimes what looks good up close, looks really bad when you back off. Since this is for a baby, I would look for a light print that has either of the colors or both in it. A white with a swirly teal or pink would probably look good. If you have access to a Joan's or Hancock fabrics, take one each of the blocks in and test them with different looks. For a baby, you might want something light, even a white tonal, then surround it with a piano key border with a lot of colors in it or just alternating the colors that are in the blocks. You've got such a good start, that there is so much you can do with it.
Edited to add: Since you are going to applique the blocks down, why not think about adding some little ribbon loops and some other interesting, tactile things for the baby to play with? I can't wait to see what you come up with.
