In brief: Autosomal recessive
You and the baby's father are both carriers for this disorder. Therefore neither of you actually has it.
Please get genetic counseling because your next children will all have a 25% chance of being born with cah. Should your child want children of his/her own, all of them will be carriers. Cah would only happen in your grandchild if your daughter/son's partner is also a carrier or has cah.

In brief: From both parents
The vast majority of cah cases are passed as autosomal recessive genes through two asymptomatic parents.
Some are x linked (male with unaffected carrier mother).It can occur as part of a broader syndrome. Discussion with your dr/metabolic specialist or geneticist will be important for your extended family & your future plans. Recurrence risk /pregnancy & other issues should be explored.
