@Rumpledfaceskin but it isn't the same information - that's exactly my point. Breastfeeding reduces the risk. Formula feeding doesn't increase it. The risk remains the same.
The link that littlepea shared shows how a formula for babies with cows milk intolerance was marketed to health professionals with zero evidence to support their claims that it improved symptoms.
I absolutely agree that this is terrible. However the SIDS comparison is the same - there is zero evidence that formula feeding increases the risk of SIDS. Even the Lullaby Trust doesn't say that formula feeding increases the risk, only that breastfeeding reduces it.

They don't even mention formula, using bottle feeding as a descriptive term instead - I assume because although there is evidence that breastfeeding reduces the risk of SIDS, in that more babies in the sample who died of SIDS were formula fed, there is no way of determining with any certainty that it was the breastmilk itself rather than any other factor (e.g. closer proximity to mother, more likelihood to safely co-sleep and be more aware of baby throughout the night, clear cot, laying on back) that reduced the risk.
Look - being completely honest about my motivations here, I lost a sibling to SIDS so it is a topic that I have done a lot of reading on and that I am really clued up on for my own kids. I FF one as I couldn't breastfeed and have managed to breastfeed the other - we're up to 6 months now. I remember the cold feeling of dread I felt when someone told me that FF increased the risk of SIDS. It's only because I was able to check the facts and understood the analysis of risk that my already elevated anxiety about not being able to BF and SIDS risks in general wasn't through the roof.
Frightening new mothers into breastfeeding, or frightening them about something they have no control over if unable to breastfeed, is just not on. It's dishonest and cruel. Even if it was true, which it isn't.
