What could it be?

On August 15th, Harper had her second MRI. My little girl is such a trooper and my husband is my rock as we go through this journey together. For this MRI we (or should I say Brian) had to hold her while they put in her IV. Sweet girl was terrified at to what was going on. Then Brian carried her as I followed to the actual room where she would be getting the MRI scan. They then put the anasthesthia in the IV and Brian and I sat there as we watched Harper's eyes rollback into her head as she drifted to her out of concious state. It was extremely sad to watch! They made us then leave and wait in the waiting room for about 45 minutes, until they called us to go help wake her up. Within 10 minutes she was awake and we were on our way home. 10 days later we went back to the neurologist to find out the results. From the doctor he said that her brain is "significantly abnormal." The white squiggly lines on the outside of the brain were more straight (they should be squiggly.) and the cerebellum (the internet part of her brain) was very thin when it should be think. He said that the reason why is that Harper has a chromosome abnormality or irregularity. He said it happens in 2%-4% of all my first time pregnancies. It is not genetic because genetics would be that Brian or myself passed it to her.

We told him that we had an appointment with a new geneticist (for a second opinion per her pediatrician) and he said that if they could not find a more accurate diagnosis then to close the door. He said we know it's a chromosome
