Dial - the reason SIDS is now so rare is because people are following the guidelines. If everyone stopped following them because it's rare then the number of babies dying would increase dramatically. There is a direct link between the reduction in SIDS deaths and people following the guidelines.
Guidelines that have been developed over years of studies of families like mine. Every baby born in our family for the last 25 years takes part in SIDS research and are on the CONI programme because two babies in the family died. The circumstances of their deaths, and the information gathered on the next seven babies has helped form these guidelines. I followed them to the letter, because every single one of them is recommended for a reason, and every single one is based on studies of thousands of babies whose parents have given consent for their data to be used so that others don't have to face what they have. This isn't scaremongering or trying to make anyone feel inadequate, it's just fact. And the fact is babies are at a significantly greater risk of SIDS if they sleep in their own room before six months.
OP I appreciate that you are planning to use a sensor pad monitor, I have one, and our babies are monitored with hospital grade heart, breathing/movement and SATS monitors too, but they don't negate the guidelines. The safest place for a baby to sleep (all sleeps, naps included) is in the same room as their parent/s.
The Lullaby Trust (formerly Foundation for Sudden Infant Death - FSID) have a wealth of information on their website and the point they push the most (it has a strap line) is 'Sleep safe, sleep sound, share a room with me'
The research programme is incredibly stressful for the families involved. It is time consuming, it involves having a paediatric nurse train you in infant resuscitation, daily charting, daily weighing, daily diarising of everything, weekly hv home visits, regular consultant paediatric appointments and far, far too many heart stopping false alarms on the apnoea monitors. But as families who have felt the horror, and been through the process the guidelines are our gift to other parents so that they don't have to do go through it.
I would urge everyone to follow the guidelines, they are there to help you keep your most precious people as safe as they can be.
