Craniosynostosis

Hello, my daughter will be 6 months old next week. At her last checkup, the doc told me her fontanel seemed to be slightly smaller and harder to find than she likes to see at this age. So now we are waiting to be scheduled at craniofacial/Seattle Children's Hospital. Both my husband and I have small-ish heads (we both wear a 6 7/8 hat size). The doc said we will likely be going to genetic counseling to find out if out kiddo has recieved any hereditary traits from us and what the chances are with future pregnancies. I'm just trying super hard to not overthink it and make myself sick with worry. Has anybody else had a little one with craniosynostosis or a like situation? I keep hoping maybe her head diameter will grow and the fontanel will open back up, but we will know more after they check her out.

Picture cause she is so dang cute❤.
