How many licks would it take? Can the iron in bars even be processed by the body? Can you do this for other minerals?
Trust me, I’m nowhere near an antivaxxer, if the pediatrician pushed even slightly harder for medicine as the solution then we’d have gone that way from the start. They were fine with us trying diet adjustments first and doing another visit soon after to see if the issue was resolved (it was).
I understand the concern though.
