My daughter is 16, has CAH, and I have never heard of seizures associated with CAH.  I’m not saying it couldn’t be, but it is the first I have ever heard that.

I cannot address the spitting up problem because my daughter was not diagnosed until she was 3, even though there were signs and she is apparently a slight salt-waster.  We were just lucky.

I am only 5’ tall and my husband is maybe 5’8".  All my family is  really short and my husband’s family is just kind of average height.  The dr would never give me a prediction of final height once she was diagnosed with CAH.  She is now 5’3-1/2" tall which is quite good with my husband and I both being short people.

Best of luck to you and your family.
