One day we went to Costco and the formula in the yellow container was GONE.
The next time we went, there was a new formula in a BLUE container.
This caused a lot of consternation.
The new formula is made by Perrigo, who also makes all the other store brand formulas. The old formula was made by Similac.
Costs are virtually identical, though a fraction of a cent higher for the new formula.
|One container yields this many prepared ounces
|Cost per container
|Cost per prepared ounce
|Kirkland Signature Infant Formula (old/yellow)
|261 oz prepared
|Kirkland Signature ProCare (new/blue)
|305 oz prepared
Despite the fact the nutrition is essentially identical to the Advantage formulas marketed under other store labels, the cost is significantly lower at Costco.
Containers and Labeling
Please note that the new formula has a larger scoop size of 8.8 grams. For those of you who prepare formula in bulk, please update your equations.
Dr Baby reports that he has not noticed any difference in his formula.
Like all formula powders, this formula mixes more easily into hot water. It is not particularly foamy. It is not particularly anything. It’s just formula!
Dr Dad admits that he finds this new blue box very difficult to open, but that’s his only complaint.
