As the parent of a new baby, the number of questions you’re going to find yourself asking are, to put it mildly, astronomical. And one of those many questions may be “is infant sleep training safe?”

The old saying about babies not coming with instructions has cemented itself in parental lore for a good reason. Even after spending nine months doing endless research on what to expect when baby arrives, as soon as we’re sent home from the hospital with our little ones, there’s an unavoidable feeling of unpreparedness.

Every baby is different, after all. So no manual, no set of instructions, no amount of coaching from friends and family, is going to prepare you for your child in particular.

And since this is just about the biggest responsibility that a human being can have, to raise another living person, we feel an incredible obligation to get it right.

Infant Sleep TrainingUnfortunately, we don’t get any practice swings or dress rehearsals. Your first run-through is the final performance, so to speak. And this only increases our dedication to solving problems before they spring up.

And since babies basically eat, poop, cry and sleep, we’re naturally very focused on those four things.

What to feed baby, that’s often a contentious subject on its own. We often find ourselves with a sudden fascination in poop that we didn’t realize we had.

Which leaves us with sleeping and crying. As an infant sleep consultant, I assure you, I’ve done a lot of research on both.

“Will My Baby Cry?”

This is the biggest question that parents have when they start infant sleep training. Infant sleep training can be done with a baby who is at least 3 months old.

This really isn’t the question they want the answer to, of course, because babies cry all the time. In fact, if a baby didn’t cry, it would be cause for concern.

What they’re really asking when they pose this question is, “How much will my baby cry?” And “will I be able to provide comfort when they do?”

Why is this the major concern with new parents? Well, naturally nobody likes to hear their baby cry. But parents nowadays are able to access a wealth of misinformation. Some of that misinformation claim if you don’t respond immediately when your baby cries, you could actually be harming them.

This wasn’t always such a contentious issue. Up until Dr. William Sears came out with his Attachment Parenting theory in 1993, parents were reasonably comfortable with the idea that leaving a child to cry for a period of time when they woke in the night was safe, if maybe a little unpleasant.

But once The Baby Book was published, a generation of new parents began to cling to the idea that it was not just ineffective, but was causing brain damage. Sears cited studies to back up his claim. But those studies looked at babies who were suffering from colic and a condition known as persistent crying. Both of these are a far cry from allowing a child a few minutes of crying time.

Attachment Parenting vs. Infant Sleep Training Advocates

And so the argument has raged on for nearly 25 years now. Attachment parenting advocates accuse infant sleep training advocates of willfully neglecting their babies for their own convenience.

It’s surprising that the pediatric and scientific community haven’t done more to prove or disprove this assertion. Espeically given the magnitude of the consequences. After all, if we’re causing our babies brain damage by allowing them to cry, even for a short period, wouldn’t almost every parent in the world alter their approach to prevent it?

One reason Dr. Sears’ claims didn’t provoke an immediate and widespread investigation was because they were hugely misleading. The Yale researchers who conducted one of the studies his research pulled from responded to his use of their work by saying, “Our paper is not referring to routine, brief stressful experiences, but to abuse and neglect. It is a mis-citation of our work to support a non-scientifically justified idea.”

Another went so far as to note in the study’s own conclusion. It stated “Our findings provide evidence that the quality of maternal behavior appears to be unrelated to this effect.” So, the mother’s response or lack of it to the condition of persistent crying was inconsequential.

That’s the argument against the original suggestion that started this whole movement. But its supporters will invariably ask, “Where’s your evidence to the contrary? How do you know it’s not harmful?”

Studies Show Infant Sleep Training to be Safe & Effective

Well, back in 2012, Dr. Anna Price, a postdoctoral researcher at the Royal Children’s Hospital’s Centre for Community Child Health in Melbourne, Australia, conducted an extensive study that followed a group of two hundred and twenty six children, measuring mental health, sleep, stress regulation, child-parent relationship, maternal health and parenting styles.

Five years later, she followed up with the families to see the if the one third of the children whose parents had employed some method of infant sleep training had experienced any of the terrifying side effects that Dr. Sears had warned of.

The result… they had not. In fact, to quote the study, “There was no evidence of differences between intervention and control families for any outcome. Behavioral sleep techniques have no marked long-lasting effects.”

But critics continue to try to shoot holes in the evidence. “The sample size was too small,” is a common complaint, no matter what the size of the study might be. “We need further study,” is another, assuming that further study supports their position, which, as of yet, it hasn’t.

In March of last year, Pediatrics published another peer-reviewed study that showed infant sleep training is both effective and safe. But this still didn’t change the mind of Dr. Sears or his followers.

For those new parents who have been bombarded with misinformation and hearsay regarding the safety and efficacy of infant sleep training, it’s yet another assurance that you can feel confident in the fact that getting your child to sleep through the night is important, safe, and beneficial to your entire family.

Because there’s one thing that everyone can agree on. A good night’s sleep is beneficial for mother and baby alike.

So the Answer is Yes, Infant Sleep Training is Safe

Sleep itself is glorious, rejuvenating, and beneficial to you, your baby, and your entire family. Focusing on your child’s sleep habits is something you can feel good about. It is a commitment that will pay off exponentially.

In short, by doing infant sleep training with your baby and yourself can both sleep soundly, knowing you’ve made the right choice.
