No Worry: The "percentile" for head circumference is a reflection of your child's head circumference comparred to others, and it is best if the "percentile" does not change greatly. 50% at 1 mo and 2 mo means your child's rate of head growth is perfectly fine. Concern only when head circumference increases/decreases by more than 2 standard deviations. Example: 50% at 1 mo, then 95% at 6 mos.

Average growth: That the kid stays at 50% is not bad, it means his head growth is following the same rate of growth that the average kid does.A drop off or jump up in the percentage could mean problems.
