writing it rough, outline should be self-evident. This is aimed to be a guide for parents that is accurate enough for a pediatrician to use as a reference. Nancy Sculerati 15:31, 14 April 2007 (CDT)

Pelvic size

To address one of the concerns raised by Nancy on my talk page, (expressing the idea of the mother's narrow pelvic size when giving birth), I suggest the following change. In this sentence:

• That means that big headed babies are born to mothers with pelvic structures adapted to walking upright, and if both mother and baby are to survive the birth process, that means the baby's brain is not fully developed in size — or complexity — at birth.

I suggest inserting "the relatively narrow" before "pelvic structures", to give:

• That means that big-headed babies are born to mothers with the relatively narrow pelvic structures adapted for walking upright, and if both mother and baby are to survive the birth process, that means the baby's brain is not fully developed in size — or complexity — at birth.

(Also inserting a hyphen in "big-headed" and changing "adapted to" to "adapted for".) I was going to also suggest moving the paragraph beginning "Even with the relatively small head diameter of the newborn," to before the previous paragraph, to move it closer to the mention of pelvic opening size, but I see that it flows very nicely into the paragraph after it, so that would probably not be a good idea. --Catherine Woodgold 15:18, 15 April 2007 (CDT)

Catherine, I think your change may be excellent, but perhaps we can hold off till more of the article gets written, and then -depending on overall length, I'd appreciate your input (and others) from start to finish-did put "relatively" in there. Nancy Sculerati 20:53, 16 April 2007 (CDT)

UI: 16205461 "Under conditions of fetal undergrowth, identified as fetal growth restriction (most commonly defined when estimated fetal weights or birth weights are below some preset percentile (third, fifth or 10th) of standardized population specific norms), the perinatal mortality rate is 6–10 times greater than that for a normally grown population, 120 per 1000 for all cases of growth restriction and 60–80 per 1000 if anomalous infants are excluded [2]. As many as 40% of all stillborns are growth restricted, including 53% of preterm stillbirths and 26% of term stillbirths [3]. Additional risks of poor fetal growth include the neonatal complications of respiratory distress syndrome, hypoglycemia, hypocalcemia, hyperphosphatemia, polycythemia, hyponatremia and hypothermia [4–7]."..."Fetal overgrowth is variably characterized as either fetal macrosomia (estimated fetal weight or birth weight greater than 4 or 4.5 kg) or large for gestational age where weight exceeds the 90th percentile for population-based norms. The primary perinatal risks of fetal overgrowth include difficult deliveries, with an increased risk for both shoulder dystocia and Cesarean sections and the traumatic injuries that can result form these dystocias [8]. There is also an increased risk of metabolic abnormalities in macrosomic neonates. The neonatal metabolic risks include neonatal hypoglycemia, polycythemia, hyperbilirubinemia and disorders of calcium metabolism [9]."
