Question: My almost 3 month
old grandson is having head measurements that are 97th percentile.
Length 25th percentile. He did the neurological sign when his fists
were clenched, and rotated in. It only lasted about a minute. He was
born at 35wks. He has had a cranial U/S and we were given a WNL report.
What else should be a concern? JoAnn
Answer: Dear JoAnn,
97th percentile means that on
a national average, 97% of babies at 3 months had approximately the
same head measurements. 25 percentile means that 25% of the babies
of that age measure his same length. When a baby is premature, the
numbers are compared with those of babies born at the same number
The developmental skills of a
premature baby are usually a little bit delayed (smiling, sitting,
walking, talking). Low weight babies may also have hearing and eyesight
problems so regular eye and hearing tests are recommended.
