My two boys age 16 & 14 both swcah were only given salt as young babies and when they started on solid foods it was gradually cut out, they took 1/2 a florinef tablet until they were about 18 months and then it was increased to 1 a day and about 3 years ago it was increased to one and a half tablets a day. I was told to always to cook vegetables in salt and to add it to their meals. Another tip that was given to me was to encourage them to eat potato chips because they have salt in them instead of sweet things and now they prefer savoury to sweet things.I don’t if this will help you but it worked for me and my boys.
