I went to my sons 4 month appt today and his head is measuring above the 97th percentile. He was an IUGR baby so the rest of his body is still small but he just has a big head. The doctor is sending him for an ultrasound of his brain to check his ventricles. He's a happy healthy little boy and is always smiling and laughing. I'm so worried about him. Just wondering if there's any other moms that have gone through this and how it turned out? There's a picture below... Do you think his head looks abnormally large?
