Often called a bed blanket or baby blanket, it introduces new risks if introduced too early. isn’t just about size—it’s about safety, development, and readiness. The American Academy of Pediatrics recommends keeping babies in sleep sacks until at least 12 months, and often longer, because loose blankets can cover a baby’s face and increase the risk of suffocation. That’s why moving from a sleep sack to a blanket isn’t a milestone you rush—it’s a decision you earn by watching your child’s behavior, motor skills, and sleep habits.
Before you swap the sack for a blanket, look for clear signs your toddler is ready. Can they roll over, sit up, and pull themselves to stand without help? Do they kick off the sleep sack regularly, even when cold? Are they climbing out of the crib? These aren’t just signs of independence—they’re signs your child has the physical control to safely manage a blanket. Also, check the room temperature. If your home is consistently warm and your child sleeps in light clothing, a light blanket might be safer than a thick sleep sack that overheats them. But if your child still sleeps on their back and doesn’t move much, sticking with the sack is the smart move. Many parents think switching to a blanket means their child is "grown up," but safety doesn’t care about age—it cares about ability.
When you do make the switch, don’t just toss a full-sized blanket in the crib. Start with a toddler-sized blanket, a small, lightweight, breathable fabric cover designed for children’s beds.

Tuck it in tightly on two sides only, so it can’t slide over their face. Use a fitted sheet under it to keep everything in place. Some parents use sleep sacks with arms out as a middle step—this lets kids practice moving their arms freely while still staying covered. And always, always keep the crib free of pillows, stuffed animals, and loose bedding. Even if your child is 18 months old, the crib should look simple, clean, and safe.
You’ll find plenty of advice online about when to make the switch—some say 12 months, others say 18, and a few even say 2. But the truth? There’s no universal clock. It’s not about the calendar. It’s about your child’s body, their habits, and how they respond to sleep.
