The most important advice regarding newborns is this – infants should always sleep on their backs. This is because if they sleep on their stomach, the risk of sudden infant death syndrome greatly increases. The advice that babies should sleep on their backs, has alone saved thousands of babies in Sweden since the 1990s. Don’t risk it!

Sudden infant death syndrome (SIDS) – our worst nightmare
To discover your child dead. An older mother I know well is fortunate enough to have her children live through the first fragile months of life. But she did tell me once after a mother’s workout she had attended, another mother discovered her baby dead in the stroller. The horror in my friend’s eyes hasn’t gone away, thirty years later. For parents themselves, I imagine that the memory of discovering your baby dead, is worse than any nightmare.
Sleeping on the stomach
I think this is important to discuss. It is important to understand why new findings about sudden infant death syndrome arouse such strong feelings. In the 1970s and 1980s, the general advice was that it was better for infants to sleep on their stomachs. As far as I understand, it was not written down as any official advice from the authorities. Parents who gave birth at the time, testified that was what everyone was told. They were told that when the child vomited, the vomit would come out of their mouths. If the child were put on their backs, the child may choke on their own vomit.
Obviously, noone wanted to take that risk. Another friend of mine, who was a mother at the time, told me how scary she thought it was putting her babies on their stomach. She was so scared they would suffocate on the pillow. But she didn’t dare do anything else. (The kids fared excellently thankfully, like most of us who spent our first few months sleeping on our stomachs)
Sleeping on the back
In 1991, a study from New Zealand was published which showed that it was exactly the opposite. It was the stomach position that increased the risk of sudden infant death syndrome, and the back position that protected it. In addition, it was clearly demonstrated that the mother’s smoking, both during pregnancy and when the baby was born, increased the risk of sudden infant death syndrome.
The following year the authorities in Sweden reviewed their advices. The advice to lay infants on their backs and the recommendation on smoking cessation during pregnancy and thereafter were launched. These were quickly followed by parents in Sweden. The number of children who died of sudden infant death syndrome decreased from 1.1 per 1000 births to 0.28 per 1000 births in three years. With 100,000 births per year in Sweden, this means a decrease from 110 to 28, or 82 lives saved each year.
Even pacifier use showed protection against sudden infant death syndrome in these early studies.
Advice on putting infants to sleep on their backs and avoiding nicotine use (smoking, nicotine gums and tablets) in parents, both during pregnancy and infancy, is still valid. Specifically, the mother who should avoid nicotine use to reduce the risk of sudden infant death syndrome. And, in the case of asthma, anyone living with a child should avoid smoking. I’ll conclude today’s post with some frequently asked questions about sleeping.
But my baby sleeps much better on their stomach…
Many or even most, babies do, I think. Had it been about the risk of slanted ears, or risk of future eczema, then priority should be given to a good night’s sleep. But now there is a significantly increased risk of sudden infant death syndrome if you put your baby on their stomach. With all the compassion and respect and understanding of how desperate you can become when babies don’t sleep, no matter how bad it gets, I think you should let your baby sleep on their back.

What about baby breathing monitors?
There is no scientific evidence to show that baby breathing monitors save babies from sudden infant death syndrome. However, there are many parents who testify that the alarm alerted them to a baby who was not breathing and they were able to rush to them. If you, as a parent, sleep better with a baby breathing monitor attached to the baby, then buy one. (I, myself, have not done so, but we are all different). The important thing is that the child should still lie on their back!
What about sleeping on the side?
According to collective knowledge, it’s better than on their stomach, but worse than on their back. When children are sleeping on their side, there is a risk the child will roll over onto their stomachs which, in turn, increases the risk of sudden infant death syndrome. If you have a child who refuses to fall asleep on their back, you can perhaps lull them to sleep on their side and then gently roll them over on their back when they have fallen asleep.
But my child can turn all by himself!
Congratulations, then the child has survived the worst risk period of sudden infant death syndrome. Continue to place the baby to sleep on their back, but every time they turn, you can relax a bit and take it as a reminder that they have passed the first most sensitive months of life.
