Maybe, if she likes salt and salts all her food.
One way i know if Nathan needs salt is if he is running a fever but has no other symptoms. I will add some salt for him or have him add some and if the fever goes away, I know it was just a salt issue.
I also have him add salt or do it for him if he is sweating alot, mostly in the summer but sometimes in the winter too.
We have noticed that if there is anything off with him, his attitude, moodiness, fever, sweating, if he just isn't feeling well or right, that could mean he needs salt and wenstart with that first and if that fixes it, we are good to go, if not, we know that somthing else could be up with his CF. If it wasn't the salt, his cough usually starts going up within a day or two, but we always start with the salt because sometimes it is just that simple.
I remember when he was a baby he would get these really high fevers at night but we could not figure out what was wrong with him. Finally one of the CF nurses asked if we were adding salt to his bottles and recommended a packet of salt (1/8 tsp) be added to his bottles. That fixed it and I was amazed at how simple that was to get rid of those fevers. We almost went to the ER because it was up to 103 and that is when she asked about the salt. I was so happy that was all it was but also felt a little stupid that I didn't know I was suppose to be adding salt to his formula. Thank goodness it was such an easy fix though.
