Are you on the fence about sleep training? Worried it could be harmful to your child?
You are not alone. Many parents feel the same.
To address your concern, Emily Oster, professor of economics at Brown University and the author of Expecting Better. “What to Expect When You’re Expecting meets Freakonomics: an award-winning economist disproves standard recommendations about pregnancy to empower women while they’re expecting" lays out the data on sleep training.
First off, she says, without a doubt, it's effective. She looks at three different meta-analyses -- one based on extinction (aka CIO), one based on timed checks (such as Ferber), and one based on the chair method (parent stays in the room) and all showed significant progress in children's sleep. Best of all, the progress persisted 6-12 months after the end of sleep training.
Next, she looked at studies that claimed that sleep training is dangerous. And what she found -- similar to my own research -- is that none of the studies that state that sleep training is dangerous are actually based on children being sleep trained.
Instead, they are based on children in long-term stressful situations. The most common was children in Romanian orphanages. These children were left in cribs for years with virtually no adult contact. They were also subjected to years of emotional and physical abuse.
Data gleaned from these studies is then extrapolated to be applied to children in loving homes who are being sleep trained.
I think we can all agree that that is hardly a fair comparison.
Looking at studies of children being sleep trained in healthy homes, she found that children's attachment to their parents actually increased after sleep training. Five years later, there was no difference in attachment between children who were sleep trained and children who were not. And as above, sleep training was shown to be effective in improving sleep.
Finally, she says that we may never be able to prove, without a shadow of a doubt, that sleep training isn't harmful BUT we have also not proved that sleep deprivation isn't harmful. Oster says, "Among other things, you could easily argue the opposite: maybe sleep training is very good for some kids -- they really need the uninterrupted sleep -- and there is a risk of damaging your child by not sleep training."
There is no research yet on this compelling point, but the research would be fascinating. Anectdotally, hundreds of parents have reported to me that their children are noticeably happier -- not just more secure but also more calm, more focused on their play, less likely to have meltdowns, and more eager to go to sleep -- after sleep training. Take it from them that sleep training is beneficial and consider: what are the costs to your child to not sleep training?
