I’m so glad you were able yo get some
Some babies just need more then others
We don’t know why
They can be full siblings and one will not need any extra niacin and the next will need the treatment
I personally start my babies on nutritional yeast day 1 just to be safe
They may not need it...
Brewers yeast will not fix a niacin issue
It can help to prevent it but only if given properly
Adding anything to water dilutes it abc can cause them not to get a proper dose
I myself use nutritional yeast
1tbs to 1 cup feed until 12 weeks. Then I sprinkle it on feed a few times week after...
