brewer's yeast vs. nutritional yeast

[bonbon]

Hi! I am about to run out of my big can of brewer's yeast that I have been supplementing in my toddler's lunch for about a year now. I'm debating whether or not to get another can or just use the nutritional yeast that I have on hand. I have been using about 1 tbsp. per day in my son's lunch. Can I use the same amount of nutritional yeast? How much should I use? should I continue to use both in his (and my) diet?

Thanks for your help!
