Jane AnnSara,
We added table salt to my daughter’s formula until she was about 1 year old. At that point she was taken off formula and put on whole milk. We tried to put salt in her baby food, but she would have no part of that so her endo told us to quit with the salt and he would check her levels later. Turns out that her levels were fine without the salt (I think that she was getting enough from her baby food) and we haven’t had to give her any since (she’s two). Hope this helps!
