Re: PG and milk is decreasing
Disclaimer- I've not talked to my pediatrician about this, and it specifically says on the box "do not use as formula" but I've given my (7 month old) son rice milk on occasion. I don't make a habit out of it, but it's worked in a pinch.
I don't know why you don't want to go the formula route, but Earth's Best does make one that's organic and not half corn syrup solids.
On the wagon. Don't sell me diapers. Unless it's something irresistible.
