I use earth's best organic soy formula. LO send to do just fine and is gaining weight appropriately. The only thing I don't like about it (other than it not being breast milk) is that it smells like raw potatoes.
I also use earth's best. The red can. We unfortunately had to switch and it was the only organic brand at the grocery store. Baby does good on it. It does smell gross though lol
We've tried literally every single organic formula and, in my opinion, Hipp Organic is the very best. Poop stayed nearly identical to when he was EBF. It's the only formula that uses real lactose not brown rice syrup. The other main difference is that it mixes immediately. Baby's Only and Earth's Best stay clumpy for a long time.
