Drew has access to the calibers and we have our personal orthotists so we can measure whenever. This has pros and cons...we get to check the progress more frequently but when there is no progress it is discouraging.
Drew has measured Porters head twice in 6 weeks. Both times he has not had any growth in the circumference of his head. (Although we do believe it is rounder in some areas.) We need a growth spurt to occur so the flat part of the head can fill in. Although, Porter is growing he has a large head for his body which could cause his head to stay the same while his body is catching up.
