I am sure the grand parents will be thrilled with these, and you certainly managed to capture his great mood. I would try a little less direct flash as it can flatten the image and be less of a natural effect. I would also have to clean up his runny nose and get rid of the food on his T-Shirt in PS. The third shot seems to have captured him going into or coming out of a blink. Otherwise a great start. Hope you don't mind the comments.
