The Ideal Age for Introducing Blankets to Babies

So, when can babies start sleeping with blankets? When it comes to a traditional loose blanket, itโ€™s recommended to wait until your child is at least 18 months old to introduce them.

Why Proper Blanket Use Matters for Babies

While children and adults can safely sleep with blankets, babies can easily become tangled in them, posing a risk. Prioritize back sleeping on a flat surface (crib or bassinet) with a fitted crib sheet , and avoid napping or overnight sleeping on chairs, couches, car seats, swings, or strollers. Itโ€™s also important to note here that loose covers, pillows, stuffed toys, and bumpers can all pose similar issues for newborns, so these need to be left out of the crib.


Once your baby is over a year old, it is safe to introduce some of these cozy items, so those adorable baby blankets and stuffed bears you bought wonโ€™t go to waste.ย 

Is Swaddling Safer for Babies Than Loose Blankets?

Swaddling is an excellent option that provides both warmth and comfort. However, swaddling is only recommended for babies who havenโ€™t tried to roll over yet. Once a baby can roll over, a swaddle can be dangerous as it prevents them from using their arms to hold themselves up while on their stomach.


If you swaddle, here are some safety tips to keep in mind:


  • Always lay your baby on their back

  • Ensure the swaddle is tight enough not to come undone but loose enough that your baby can still move their hips easily

When to Stop Swaddling

As we mentioned, itโ€™s only recommended to swaddle your newborn until they start to show signs of rolling over. Sometimes, this can happen as early as two months, so youโ€™ll need an alternative before your little one is ready to switch to a blanket.


One idea is to swap the swaddling for layering. A general rule of thumb for dressing your baby in layers is to opt for one more layer than you would feel comfortable in.


Or, you can also give sleep sacks a try.

What Are Sleep Sacks?

Aย  baby sleep sack ย is a wearable blanketโ€”imagineย sleeping bagsย with sleeves or openings for your little oneโ€™s arms. Sleep sacks can be an excellent option for babies between the rolling stage and their first birthday (or those who otherwise arenโ€™t ready to transition to a blanket).

Sleep sacks also work well for babies on the move. Their arms are out, allowing free movement, and theyโ€™re still able to kick their legs around.

Ensure you buy a safe sleeping sack in an appropriate size and TOG for your baby, and youโ€™re ready to provide your little one with warmth and comfort. You can even continue to use sleep sacks after your childโ€™s first birthday.

Transitioning Your Baby to a Loose Blanket

When your baby is ready for their first blanket, start with something thin and lightweight, and keep these safe sleep tips in mind:


  • Avoid thick blankets to reduce the risk of accidental suffocation and overheating

  • Choose a material thatโ€™s soft, breathable, and designed for sensitive skin

  • Opt for blankets without ribbons or strings to reduce potential safety risks
