Craniosynostosis ??

Just had our 4 month appt. the doctor is concerned that my babies sutures have fused together already and may need surgery. I noticed at his 2 month appt that his head was shaped funny and quite large. We now have to go to a nuerologist to see what the next steps are. Have any moms out there gone thru this? Has your doctor ever been wrong and you worried for no reason? I'm going crazy! I don't want my baby Dax to have his skull broken apart :( but I know his brain can't grow without it (if that's the real problem). Please help! I included pics of his head shape.
