Hi Jaimie.  Sorry you're having this worry.

You may have already seen this - a head circumference chart.  At birth,  he was right on the 1 percentile line for head size.

Now,  he's well below the chart for his age.  Typically,  when there's a growth concern,  watching the baby maintain their percentile rank - even if it's very low - is usually considered acceptable.

How is he doing developmentally?   Are there any concerns there?


Best wishes,  waiting is so hard.
