We have dissolved salt tablets in Loghyn’s formula since she was 5 days old (she’s now 9-1/2 months).  It’s in everything she drinks . . . formula, juice, water . . . all in the ratio of 1:8 (tablets to ozs).  Are you only putting it in 1 feeding?  or all?  If you are only giving it to her  once a day, maybe try splitting the amount up into smaller doses in every feeding.  Then it wouldn’t be so salty & she might drink it better.

Good luck!!
