From the OP: So the kid is old enough to roll herself. This gives an approximate age for the child. (Three months, rare; four months frequent; five months, typical.) The peak incidence for SIDS appears to be between two and four months, so possibly just before the baby develops the capacity to roll over.

Wee ba is now 6 1/2 months old, she’s trying her hardest to wriggle, push, drag herself around awake or asleep. She’s in the best of health and has been since day one save a small dose of thrush. My girlfriend has had two babies before and remembers so many differing offers of advice over the years to prevent all sorts happening to babies. I’m surprised I survived myself!

SIDS is commonest between one and five months, and reaches its absolute peak about 2-1/2 months of age. SIDS becomes much less common after 6 months.
The official definition of SIDS is “the death of a child below the age of 1 year, in whom a complete autopsy, review of the history, and scene investigation reveals no cause of death”. But I almost never see SIDS beyond six months. When I hear that there is a dead infant for autopsy at 7 months of age, I immediately start to worry. Pneumonia from unsuspected dangerous virulent organism? Child abuse? On the other hand, if I hear (as I do much more commonly) that a dead infant for autopsy is 2.5 months old, I think “SIDS” by reflex.
No one knows what causes SIDS, and many ingenious theories have bitten the dust in the past. However, everyone agrees that it is two things combined: a vulnerable child, and an environmental influence. The vulnerability is clearly age-related, also gender-related (it can happen to girls, but boys are more susceptible), also history-related (twins and premies are more susceptible than full-term singlets), and also race-related (AfricanAmericans have a higher rate than Caucasoids, and American Indians a higher rate than African Americans).
Among the environmental influences are sleeping face down (I’ve never had a face-up SIDS), being wrapped up too warmly, winter months, and having parents especially the mother who smokes. Pushkin, do you smoke?
The danger of crib death is much decreased by 6 months. I have never had kids, so can’t tell you what to do. But if I knew what I know now about infant death, and had a wriggling 6-1/2 month old who was barely sleeping under a blanket in the summer months, and I didn’t smoke, then I think I’d let her sleep wherever the heck she liked.
