One kidney question!!! 7 month old baby 👶

Marilyn

My baby boy was born with one kidney and we were told it’s best to limit his salt intake or better yet to not give him salt at all in his foods. I DO NOT want to Incorporate salt in his foods at all. My mom decides to give him beans with lots of salt in it and before i realize there was salt in it he has already eaten about 5-6 spoonfuls. I am beyond angry and worried. It may sound like a stupid question but will it affect his one kidney because he ate those beans with salt one time?
