Hmm, that's just made me look up the German advice since I live here. Seems to be:
Place baby on their back on a flat surface
Use a baby sleeping bag. If you use a blanket (not recommended) tuck under armpits and do feet-to-foot.
In parents' bedroom - most had no time suggestion but a couple of sites suggested for a year, one for 6 months.
Nothing in cot
Air-breathable, firm mattress designed for babies
Not bedsharing
Cool room temp, no hats, etc.
Don't smoke
Recommended to breastfeed
Regular health check ups for baby
The main differences to UK advice I can see are:
The length of time in parents' room, which I highly suspect is cultural, actually, rather than being based on different evidence. Plus it was almost universally worded as being "in the parents' bedroom" rather than "in a room with you", so does not imply daytime sleeps or early evening sleeps.
Regular health check ups and ensuring vaccination - this one is interesting, as I didn't know that vaccination had been shown to reduce SIDS rates. That could be very useful information to share with the UK population actually. I definitely came across scaremongering stuff at the time which linked vaccination to SIDS!
The mattress advice, which I find quite curious. They aren't as keen on the brand new mattress thing although it's recommended, it's not seen as absolutely essential like it is in the UK - I've found a couple of sites which actually refute this particular claim (though they say a new mattress is a good idea, it's not for SIDS prevention reasons). Instead they go with an approach of ensuring that the mattress is well ventilated so open cot styles rather than more closed, solid types and particular materials to make the mattress out of. This is related to fears about CO2 rebreathing, which is one of the theories about why stomach sleeping is dangerous.
Use of sleeping bags. I know they are popular in the UK but they seem to be marketed as essential here.
BTW, UK advice says:
"The safest place for your baby to sleep for the first six months is in a cot in the same room as you." (NHS)
"Place your baby to sleep in a separate cot or Moses basket in the same room as you for the first 6 months, even during the day." (Lullaby Trust)
"Ensuring that infants sleep in the same room as their parents [reduces SIDS]" (Public Health England)
Actually, I hadn't realised they'd added that addendum "even during the day" to the Lullaby Trust recommendations. So it seems that it is official advice in the UK.
Out of interest there was recently a discussion in my local group where an American parent wondered where she could buy a rock-n-play which is what she said all of her friends back home used for their newborns. I'd no idea what this item was but I googled it, and it's basically a rocking crib which is on a slope, so elevated at the head end. It's interesting because the UK and German regulations specify a flat surface yet it seems that it's not considered as important in the US. The US recommendations from CDC, NIHCD and AAP are:
Place baby on their back
Firm surface with no loose bedding
No objects in the cot including bumpers
Room share for at least 6 but preferably 12 months
Breastfeed
Regular health check ups and vaccinations (See that German one again)
No smoking
Don't overheat baby (but no recommended temperature, just "comfortable" - UK and Germany recommend 16-18C.)
Use a dummy (On 2 out of 3 sites)
Don't co sleep ever (much more stringent about this than the other two)
Skin to skin immediately after birth
Don't use breathing monitors or products marketed as reducing SIDS risk
The last one is the most interesting to me. I don't know if it's because products for babies are required to undergo less testing before being sold in North America than Europe.
