@sarebear1992 Here’s one. Just an example. From my read overall, the literature is very much still evolving (and again, it’s still so difficult to account for all potential confounders!!). It’s truly a complex and emotionally fraught research question. (Impressive how so many Redditors have it all figured out /s
)

“Previous systematic reviews and meta-analyses of observational studies have suggested that breastfeeding more than 3 months (10,11), and exclusive breastfeeding for more than 2 weeks (12), are associated with an approximately 15–30% lower risk of type 1 diabetes.”
“Our key findings are that children never breastfed had a twofold increased risk for developing type 1 diabetes, and that—perhaps most important—no clinically relevant difference in risk was found for those with different durations of either full or any breastfeeding among those who ever breastfed.”
Also note:
“In line with previous population-based studies (13,15), we found no evidence for an association between age at introduction of formula and development of type 1 diabetes. This is also concurrent with results from the randomized Trial to Reduce IDDM in the Genetically at Risk (TRIGR) study, showing that weaning to a highly hydrolyzed formula, compared with regular cow’s milk formula, was not associated with a decreased risk of multiple islet autoantibodies (24).”
(OP, this is all still consistent with the overwhelming assertions that formula is perfectly good for you to switch to!!)
