Here's the crack.
Formula is less than ideal. But it's also a lifesaver. You can offset any negative effects when they start weaning.
Of course we don't actually know if or what the negative effects are because it's almost impossible to study in to adulthood. But we know seed oils are bad, for example, and cause chronic inflammation. But it is reversible. And the fact is that formula will feed and nourish your baby in other ways.
Kendamil Organic uses whole organic milk, and doesn't have the emulsifiers and stabilisers that other formulas have. Only the powdered one though, the ready to feed bottles obviously need stabilisers to increase shelf life.
It also has a mix of 3 oils, one of which is coconut oil so I suppose you could argue it has a third less seed oils than other formula.
I fed DC1 exclusively on kendamil - as BFing didn't work out and he's a strapping young lad.
DC2 is on breast milk and I supplement with formula because even though I was desperate to BF and I'm pretty crunchy in most ways - I actually hate breastfeeding!
I really wouldn't worry, you've laid the groundwork with breastmilk and little one will be absolutely fine!
