Compare per 100g or per 100 calories. Suggested serving amount implies an amount that is considered appropriate to consume at one time. Which is fine for non-essential foods but nonsensical for baby formula.
BTW manufacturers can (and do) play games with the suggested serving amount to make their product appear healthier or more desirable. Standardize on a common denominator for a product category and stick to it. Then, if needed, call out how many units of the product are in that standard size.
