The intensity of response is >greatest in prematures of a larger weight. What a coincidence! I tried this on premature twins (nice big 6 1/2 pounders)yesterday and was able to get it over and over again in both (one hand only, I hadn't read your post at the time). So I started wondering when this reflex appears and when it fades out, thinking maybe babies born earlier might exhibit it more strongly than full-term babies (just a thought)....
