I had a sonogram (actually two) because my ob thought the baby's head
is too small (3rd percentile) and the baby itself is small (7th
percentile). Now he's concerned about the head circumference and wants
me to get a second opinion with a specialist and take a level-2
sonogram. So this will be my third sonogram.

Any opinions, experiences?
If you need any more details please ask.

Thanks.
