 Prevent a Baby From Rolling Over in the Crib

As a new parent, you're filled with wonder as you watch your little one grow and develop daily. One of the milestones you've been anticipating with excitement and maybe a little anxiety is when your baby starts rolling over.


While rolling over is an important developmental skill, it can be nerve-wracking when it first happens in the crib. You want your baby to be free to move and strengthen their muscles, but you also want to ensure they remain safe while sleeping.


The good news is there are a few simple tips to prevent your baby from rolling over in the crib before you're ready while still allowing them opportunities during tummy time to master this new skill. With the right precautions, you'll be able to rest easy knowing your baby

When Do Babies Start Rolling Over?

Most babies master rolling over between 4 and 6 months. Some rollover earlier, around three months, while others take until seven months. Every baby develops at their own pace, so don't worry if your little one rolls over on the later end of this range.

Back to Front

Rolling from back to front, or "belly", usually comes first. Babies have more control over their top half, so they can swing an arm over and push off with their legs to get onto their belly. Once on their belly, they'll start pushing up with their arms to improve their strength.

Front to Back

Rolling from belly to back takes more coordination and strength, often coming a few weeks after back-to-belly rolling. Babies have to lift one hip, twist their trunk, and swing a leg over to get onto their back. For new parents, front-to-back rolling is a relief since babies can now roll themselves off their bellies if they get into trouble.

Precautions to Take

Once babies start rolling, be very careful to take precautions to prevent falls or injuries:

• Always place babies to sleep on their backs. Back sleeping is the safest position for infants. • Remove loose bedding, bumpers and toys from the crib. Only a tight-fitting sheet should remain.

• Make sure the mattress is at the proper height and fits snugly in the crib frame.

• Never leave a baby unattended on a changing table, bed or other elevated surface.

• Install baby gates to block open stairways.

• Cushion hard surfaces like wood or tile floors in case of falls.

• Keep babies in a safe, enclosed space when playing.

With the proper precautions taken, rolling over is an exciting milestone and helps babies strengthen their bodies and explore the world around them. Enjoy this new stage of development!

Dangers of Baby Rolling Over in the Crib

Rolling over becomes an important milestone as your baby gets stronger and more mobile. However, rolling over in the crib also introduces some dangers that new parents should be aware of.

Suffocation and Entrapment Hazards

The biggest risks of a baby rolling over in the crib are suffocation and entrapment. Loose bedding, blankets, toys, and bumper pads can all pose hazards if your baby's face becomes covered or tangled up. Once your baby starts rolling over, remove all loose items from the crib. Only use a tight-fitting sheet and wearable blanket or sleep sack.

Falling Out of the Crib

If your baby starts rolling over, they are likelier to end up on their tummy. This new position and increased mobility means your baby is at a higher risk of falling out of the crib. You'll need to lower the mattress to the lowest setting and ensure all sides of the crib are properly secured and locked in place. Removing any mobiles or crib gyms, your baby could grab onto and pull up on is also a good idea.

Sleeping in an Unsafe Position

Rolling onto the tummy or side can put your baby in an unsafe sleep, especially if they cannot roll back over. The safest sleep position for babies is on their back. Gently roll your baby onto their back if they end up on their side or tummy. You may need to do this repeatedly until they learn to roll onto their back independently.

Lack of Oxygen

If your baby's face becomes covered or they end up in a position where their nose and mouth are obstructed, it can lead to a lack of oxygen. Check on your baby frequently after they start rolling over and make sure their face remains uncovered and their nose and mouth are clear. Gently reposition them if needed.

By taking simple precautions and closely monitoring your baby, rolling over in the crib does not have to be dangerous. With time, your baby will get better at rolling and be able to change positions on their own to avoid hazards. But until then, new parents should take extra care and be cautious.

Using a Sleep Sack to Prevent Rolling

A sleep sack is one of the best ways to prevent your baby from rolling over in their crib. A sleep sack, a wearable blanket, is designed to keep your baby warm while restricting their movement. Unlike loose blankets, a sleep sack won't bunch up around your baby's face or cover their head. It also prevents their little legs from kicking the blanket off, helping them stay comfortable throughout the night.

Choose a Sleep Sack Specifically Designed for Sleeping

Look for a sleep sack specifically meant for sleeping, not just lounging. These sacks are designed to be worn snugly so your baby's movements are limited. Popular brands like Halo, SwaddleMe and Miracle Blanket offer sleep sacks with safety in mind. You'll want a swaddle sack with Velcro or snap closures for the first few months to keep your baby's arms snugly at their sides. Once your baby starts rolling over, you can transition to a wearable blanket sleep sack that leaves their arms free but still prevents rolling.

Double Swaddle for Extra Protection

For newborns, you can use a swaddle sack and swaddle their arms to prevent rolling. Place your baby in the sleep sack, then swaddle their arms snugly at their sides using a muslin blanket. The double swaddle, with their legs remaining unrestricted in the sleep sack, will make it nearly impossible for them to roll over until ready. Once your baby starts pushing up or rolling during tummy time, it's time to stop swaddling their arms for safety.

Rollover Bumpers for Active Sleepers

Rollover bumpers can give you extra peace of mind if your baby is an active sleeper. These wedge-shaped bumpers slide under the mattress to prevent your baby from rolling onto their stomach. They're made of a breathable mesh and shouldn't be a risk for suffocation or entrapment. However, bumpers should be removed from the crib for safety once your baby can sit up, push up or crawl.

Using a combination of swaddling, sleep sacks and rollover bumpers in the early months is the best defence against an overly active baby who wants to roll over before they're ready. With close supervision and by following safety guidelines for each product, these tools can help ensure your baby only rolls over when they have enough head and neck control to do so safely.

Adjusting the Crib Mattress Lower

Lowering the mattress in your baby's crib is one of the best ways to prevent them from rolling over before they're ready. As babies get older and more mobile, they can roll from their back to their stomach and sometimes back again. This new skill means it's time to adjust their sleeping environment.

Move the Mattress Down

The easiest thing you can do is lower the mattress in the crib. This makes it harder for the baby to gain enough momentum or leverage to complete a roll. As a general rule, the mattress should be at its lowest level when your baby starts rolling, then move it down one level at a time as they master each new mattress height. Gradually progressing to the next level ensures the baby is ready for more mobility and prevents frustration.

Consider a Breathable Mesh Liner or Bumper

Another option is to install a breathable mesh liner or mesh bumper in the crib. These provide an extra layer of protection around the edges of the mattress to prevent limbs from getting stuck between the slats or in the corners without posing a suffocation risk like traditional crib bumpers. The breathable mesh material and secure installation means the baby cannot pull it into the crib.

Offer Distractions

Placing engaging toys, activity gyms, or mobiles in the crib may help distract your baby from rolling. Giving them interesting things to look at, swat and grab onto can keep them occupied on their back for longer periods. Rotate different toys to maintain their interest.

Supervise Baby During Awake Times

Always provide close supervision when the baby is awake and practising rolling. Spot them quickly if they start to roll and gently roll them back onto their back, reminding them that it's not quite time for that new skill set. With consistency, they'll get better at staying put on their own.

The key is being proactive and adjusting before the baby masters rolling completely. Keep trying different techniques until you find what works for your little one. Their safety and development are the top priorities during this transition.

Transitioning to Arms Out Swaddle to Limit Mobility

Once your baby starts rolling over, it's time to transition them to an arms-out swaddle or sleep sack to limit their mobility in the crib. This helps ensure they stay on their back while sleeping, which is the safest position for infants.

Loosening the Swaddle Gradually

The key is slowly getting your baby used to having their arms out of the swaddle. Don't go cold turkey and suddenly have your arms completely free. Start by leaving one arm out of the swaddle for a few nights. If they seem comfortable, try leaving both arms out but swaddling their torso snugly. This helps them get used to the feeling of their arms being free but still provides the snugness of the swaddle that they find comforting.

Use a Transitional Swaddle or Sleep Sack

A transitional swaddle or sleep sack is a great option once your baby is ready for both arms to be out. These provide just enough looseness and mobility for your baby's arms but keep them snug and contained so they stay on their back. Popular options include the Halo SleepSack Swaddle and the Nested Bean Zen Swaddle. These help your baby get used to gradually having more freedom of movement.

Follow Safe Sleep Guidelines

The most important thing is to continue following the ABCs of safe sleep:

•Alone - Your baby should sleep alone in their crib without any blankets, toys or other items that could lead to entanglement or suffocation.

•Back - Always place your baby on their back to sleep. This is the safest position to reduce the risk of SIDS.

•Crib - Your baby should sleep in a safety-approved crib with a firm mattress and fitted sheet.

• Don't use loose bedding, bumpers or toys in the crib.

By loosening the swaddle gradually and using a transitional product, your baby will get accustomed to more freedom of movement while staying safe in the recommended back-sleeping position. With time and patience, your little one will become quite the pro at rolling and moving around, so enjoy this stage while it lasts!
