My daughter will be 5 this summer. As an infant we needed to add salt water solution our pharmacy so nicely made up for us with distilled water and salt tablets. When my daughter was in NICU because she was not diagnosed at birth (no newborn screening PLUS they brushed off her ambiguous genitals as something else even though her sodium levels showed dehydration at release, I found out later) Anyway, while in NICU, the doctor played with different doses of salt water to see what she would tolerate. She needed of course to keep it in a certain range. We added it to her formula and she was fine with the taste. At around age 2 we took her off of the sodium water completly. Some do it earlier but she was never a good eater for me. They take them off when they start to eat table food completly. She has automatically chosen salty foods in her life. Pickles, ketchup on ketchup, ect. Someone actually got her a bottle of ketchup for her first birthday as a joke because when she was in her walker and I would open the refrigerator, she would zoom up to the fridge door and swipe the ketchup bottle to suck on! (of course after that it was hers to keep) Besides that, when she gets the emergency fever, vomitting, ect. stuff, we are NOT instructed to give her more of her Florinef loike we do for the Cortef. Florinef is the other medication that she is on besides Cortef because she is a salt waster. I was told that Cortef DOES have a salt retaining tendency too. In times of illnesses, like any other CAH child, we need to push the pedialyte when she gets the emergency list of illnesses. That and heat really gets to her. We had talked earlier about pushing salty foods and water when the temp. is high outside earlier on the board. So I keep with her a bottle of water outside with a cap to protect from bees climbing in it. Anymore questions, please ask. I am sure others will add more good stuff. Good luck!
