Um, U followed by pareve is the Kosher dairy symbol?
I copied straight from the site – I hadn’t noticed that part!
Unless you have health concerns with milk-based formula, I’d avoid the soy. Better to drink cholov stam formula than have these side effects.
Very possible, especially if the baby is exclusively on soy. If it’s a supplement to nursing, it might not be an issue (I haven’t seen the studies; if CY formula wasn’t available, I’d do more research).
