Jasper's talking

Jasper has put all his energy into the physical, and not so much the verbal. At this point obviously he is a little late at some of his language skills at this point. We have been trying hard for the past month or so to get him to pronounce some of the things that he typically avoids like J and G. A little boy at daycare was talking to Jasper the other day and said, "Jasper, you sound so different!" Jasper responded with, "Me no muh mo memuh!" Translation: "I don't sound so different!" Sadly the boy understood, Miki understood, we would understand and Lucy too. Thus is the crux of the problem.
