The fact that there was no height or skull growth makes me immediately suspicious about endocrine problems. I have to assume that the ped/family practitioner involved ordered x-rays and blood work in preparation for a referral to endocrinologist. The slight developmental issues fit with the hypopituitarism differential diagnosis, as do the early feeding challenges. If babies generally double birth weight by 6 months and triple it by one year, this babe should be within striking range of 21 lbs and, more importantly in this case, growing taller and "bigger headed". I just checked a site on the web for info about the hypopituitarism that will be of interest to you. Good nutrition is obviously of importance but the numbers indicate a much more involved issue than a case of too few calories. Here's the site: www.mc.vanderbilt.edu/peds/pidl/endocr/grohorm.htm.
