One of my best friends uses this. Her son had digestion issues and had to use a particular brand and formulation of formula and then the shortage hit.. she switched to this and chronic sinitus he was experiencing resolved overnight.

She swears by this now.

My recipe is get mom to bear a nipple, put baby's mouth on nipple. That's it. Nothing to buy, nothing to make.

They recently started allowing European organic formula powder to be sold in the US, so I picked up some of this: Kendamil Organic Stage 1.

The only really questionable ingredient are some seed oils, but my wife plans to breastfeed and only use this stuff at first/when absolutely necessary. It doesn't have corn syrup, soy, or anything GMO.
