Can a child become a gourmet expert?
Parents make the mistake of comparing their own tastes to those of their child and forget that we each, in fact, experience food based on our own lives and experiences. For a baby, who has only had milk for the first 6 months of its life, everything is new, everything is original! We now know that infants are able to tell even very similar flavours apart. In addition, before 12 months it is not recommended to add extra sugar or salt. For older babies, it's different. Physiologically, they are more robust and their kidneys better able to filter out salt. And, more importantly, their food environment is totally different since they have begun to share the table with their parents and eat the same foods as them.
That's when babies start to compare tastes! You can't therefore keep giving them the same meals as before. They're allowed to try more sophisticated recipes, with small amounts of salt.
