Why is that so important? How does that look different to those that are forming the feds?

Yeah.

So by and large, your mode of feeding has a way, way, way stronger effect on the baby's microbiome than their mode of delivery.

And the exclusivity of your breastfeeding has, in fact, the strongest determinant of any factor on the baby's microbiome than anything else, whether it's mode of delivery, whether it's genetics, whether it's the mother's diet, anything else that the amount of breast milk a baby receives has the strongest effect of what their microbiome looks like.

And so if you think about it, it's really important.

So we think about this environment in which there's new species coming in, these new, let's call them plants or bacteria, whatever you want to call them, in this jungle, in the baby's gut.

And they need nutrients to grow, right? They...

But if we do have a baby that has the antibiotics or perhaps is born by cesarean or a mum that chooses not to breastfeed or can't breastfeed, is there a place for probiotics? What's your kind of thoughts and experience?
