My personal opinion is that the advantages of co-sleeping far outweigh the risks. It is much less stressful for both the parents and the baby. My wife simply slept topless, turned (half-sleeping) to our baby whenever it was crying, and immediately fell back asleep.
That’s why the SIDS reduction measures are mostly ‘sleep on the back, in an empty crib, with nothing soft around’.
But it’s much easier to tell a grieving parent that there’s nothing they could have done, than that their baby got unlucky and suffocated to death.
Swaddling the baby and forcing it to sleep on its back, may have a tiny statistical benefit for SIDS, but it causes tons of problems at a time when people are taxed to the limit of their abilities.
We could reduce the incident of breast cancer by removing every woman’s breasts, but that would be an improper risk assessment.
The biggest factor linked to SIDS is poverty, and after that it’s stuff like going to bed while under the influence of drugs and smoking.
And it was fantastic. No crying, no separation anxiety. Feeding was easy, so we all slept well.
We went from sleeping 2 hours per WEEK (I cannot describe to you how it felt), to getting 8 hours on the first co-sleep.
Never looked back.
