Have they taken any urine samples? She could be getting bladder infections. Because of their urethra is "U" shaped sometimes this causes urine to back flush into the bladder. Causing annoying bladder infections. Every time my daughter had a fever as an infant, they would take a urine sample and check for infection. Be sure to ask. Hang in there. It gets easier when they get older and can tell you when they start to not feel good. Be sure to stress dose her when she gets these fevers. But make SURE they are checking her urine for infections. Our ped. always said fevers in infants are very important to follow. CAH or not. I suggest taking her in to just be sure. Good luck. Keep your faith, that is what gets me through it all. Prayer. God bless.
