Newborn Sleep: Common Mistakes New Parents Make

We hate to break it to you, but your dozy, peaceful infant who simply falls asleep, milk-drunk, after feeding may not always be this way. The first few weeks (or even months) are not always indicative of the kind of sleeper you happened to score in the newborn sleep lottery. Some babies randomly sleep through the night early on (congratulations!), but it doesn’t mean this will continue indefinitely.

Have you weathered the four-month sleep regression yet? Yeah, you might want to read up on that. (Sorry.) And even though nursing to sleep or rocking to sleep before naps and bedtime might be working for you now, know that sometimes IT JUST STOPS WORKING.

We get it, falling asleep on the sofa with an infant curled up on your chest is one of the best feelings in the world. Many an exhausted new mom has nodded off for a bit while her sleeping baby is sprawled across her lap or nestled up all warm and cozy on a breastfeeding pillow. But this kind of co-sleeping, on a couch or armchair, is a serious newborn sleep mistake. It's way more dangerous than co-sleeping in a bed, due to the risk of dropping or smothering the baby.

The Canadian Paediatric Society and the Public Health Agency of Canada both recommend room-sharing, not bed-sharing, for the first six months. If you’re exhausted and worried you might nod off while feeding, the safer plan is to move your baby back to their own crib, cradle or bassinet as soon as possible.

This is a contentious one, because we’ve all been there: Your baby conks out in the car seat while you’re driving home or running errands, and the beauty of the bucket seat is that you can pop it out and transfer your sleeping infant inside for the remainder of her nap. But according to the AAP, allowing an infant to sleep in a bucket car seat that’s been placed on the floor or clicked into a stroller is a safety hazard, as the baby’s head can fall forward and cause something called positional asphyxiation.

Due to the angle of the seat design, it’s much safer to let your newborn nap in the car seat while it’s attached to the base and installed in the car. Letting your baby sleep in a car seat overnight when you’re not awake enough to check on her is a serious baby sleep mistake. In fact, experts actually recommend limiting the time your baby spends in a car seat, bouncer or swing to 30 minutes, mostly for developmental reasons (it restricts motion) and the risk of developing positional plagiocephaly (aka flattened head syndrome). However, we’d like to acknowledge that this 30-minute maximum is downright impossible on road trips, for parents who have long work or daycare commutes, or when the swing is truly the only place you can get your infant to nap.  We’d love to see more research on this recommendation.

This one’s pretty easy to follow: Don’t use crib bumpers. Health Canada and the Public Health Agency of Canada both advise keeping a baby’s sleep space free of soft items, including bumper pads, pillows, loose blankets and sleep positioners. They've actually been banned in the US, after years of doctors lobbying against them. Yes, some babies flail around a lot in their sleep, especially when they’re on the verge of learning to roll, crawl or walk. But they're unlikely to seriously injure themselves by bumping their heads on a crib rail.

While those "breathable" mesh bumpers do a good job of keeping soothers (and little hands and feet) from poking out of the crib slats, they are also not recommended due to the risk of entanglement and strangulation. Also, word to the wise: older, more mobile babies can stand on bumpers and use them as a step when they’re trying to monkey their way off the crib. And while we're at it, you shouldn't use a DockATot or "infant lounger" for unsupervised sleep inside (or outside) the crib, either. They're technically no longer available in Canada, but similar products are still on the market.

Baby monitors are super useful, but they're no substitute for avoiding baby sleep mistakes. If you hear your baby stirring, a quick peek at a video monitor can tell you if it’s a full-fledged wakeup, or just some nothing-to-see-here squirming. Sometimes you can get back to your Netflix without opening the nursery door, or quickly pop a paci back in before the situation escalates. But some parents are taking the high-tech baby monitor trend to the extreme, buying wearable vital-sign devices that measure an infant’s heart rate and oxygen saturation levels.

The AAP advises against using these kinds of cardiorespiratory monitors, as well as the sensors that go under the baby’s mattress, because they can cause false alarms, which make parents anxious and lead to unnecessary ER visits and tests. They can also make parents less focused on safe sleep practices because they believe the device will alert them to any and all problems.

The Public Health Agency of Canada, Health Canada and the Canadian Paediatric Society all give versions of the same advice: back to sleep, firm flat surface, and nothing soft in the crib. Always put your baby into the crib on their back (not their side or her tummy); keep blankets and pillows out of the crib; and stop using swaddles once your baby has learned how to roll. The Canadian Paediatric Society also advises stopping swaddling once your baby shows signs of trying to roll.

Newsflash: Your baby is always teething. Or sick with a cold. Or coming down with something. Or recovering from something. Or over-tired. Or suffering from Unexplained Fussy Baby Syndrome. OK, we made that one up. But it’s kinda true.

Getting a newborn to sleep can feel like a Sisyphean challenge. Know that one day your precious baby will go back to bed, and you will get a good night's sleep. One day.
