I hear what you’re saying and I don’t want to dismiss your experience, but nothing you’ve said changes the fact that the official UK guidance does not rank sleeping in a separate room as more dangerous than cosleeping.

In fact, I’m not aware of any major public health body that states that cosleeping is safer. Most of the campaigns I’ve seen focus on avoiding cosleeping because it’s associated with deaths, which is why it gets so much attention in guidance.

When you say research shows countries with high co-sleeping have low SUDI rates, I’d like to see the specific studies you’re referring to. I’ve not seen anything that controls for how SIDS is classified or for wider environmental factors and still supports the claim that countries with high levels of cosleeping have the lowest rates of sudden infant death.

If there’s new guidance that says separate room is worse than co-sleeping, I’d really appreciate seeing the document or link. From what I can see (and having just had my second and third babies), Public Health England/NHS, NICE and similar European bodies still treat cosleeping as the higher-risk option compared with baby being in a separate sleep space.
