I agree with what's been discussed.
I think one issue is the right dose for the right person in the right formulation. We have been using a lot of the infant formulation for older children for convenience. With my immigration background, I think you just have to conserve and use what you absolutely need to, when you need to. Guidance on when to use infant formulation and when to teach our older children to swallow tablets is one way, as well.
I've had kids in the ER who would drink down the whole infant bottle, because they won't swallow a tablet, and the dosage is such that you will consume the whole bottle in one shot.
