I'm new here but I wanted to also offer some cause I know how you feel. I went through the same thing with my son who is 11 months and perfectly fine. He had to have a sonogram by 2 months cause the doctor thought he might have liquid in his brain due to how fast his head was growing. It turned out he has a big head. I was also a mess. Good luck
Thank you so much for sharing your experience! I hope Reilly has a big head too!
I know it's easier said but try not to worry too much. DD's height was off 2 1/2 inches for the hospital to the pediatricians office at her first vist. I doubt she was shrinking just sloppy measuring. They were also concerned that her head was too small and they had to watch it. At her 6 month chekup I got told her head is big for her body...
