Babies should sleep in their beds first three months to reduce risk of SIDS
In addition to sleeping on their backs, infants should sleep in their own beds for the first few months to reduce the risk of sudden infant death. A new doctoral thesis at Sahlgrenska Academy at University of Gothenburg has explored these issues.
In the early 1990s, the Swedish National Board of Health and Welfare went out with advice to new parents to reduce the number of children who die each year from SIDS.
The advice stated that children sleep safest on their backs, that smoking during pregnancy is a risk factor, that children should not be kept too warm, that they should be able to move freely and that breastfeeding provided a certain amount of protection.
The preventative advice led to a sharp drop in the number of deaths from SIDS; from over a hundred children annually, to about twenty deaths per year in more recent years.
Children sleeping with their parents can be a risky situation during the first months. One of the thesis' four studies examined co-sleeping.
One out of five children slept with their parents at 6 months of age and it was even more common if the child was breastfed, had difficulty sleeping and woke often as well as if the mother was a single parent. If the child used a pacifier, co-sleeping was less common.
The thesis shows that current advice is relatively well followed, and that only one in 20 infants are laid down to sleep on their stomachs. Babies were more commonly sleeping on their stomachs if the mother was unemployed, smoked during pregnancy, if the child was irritable, shared a room with siblings or did not use a pacifier.
As sudden infant death syndrome has become less common, smoking has become a greater risk factor.
Now, it is no longer more common for deaths during the winter months and the average age of sudden infant death has lowered from just under 3 months to 2 months, since introduction of the new advice in the early 1990s. ■
