My 5 year old (CAH salt waster) has never had strong salt cravings though will salt her food when the shaker is on the table. But now for the last few days I have found her in the pantry eating the salt straight from the shaker and  eating the sea salt from the canister. Is there any reason why these cravings may have all of a sudden popped up. She seems fine, hasn’t been involved in any extra sports and the weather has not been super hot. It is just a new behavior for her. Thanks
