Why Does My Toddler Keep Kicking Off Their Blanket at Night?

If you've ever stumbled into your toddler's room at 2am to find them uncovered, sprawled out, and somehow still sleeping - you're not alone. This is one of the most common complaints in every parenting forum, subreddit, and mommy group.
And the instinct is always the same: add more layers. Get a heavier blanket. Tuck them in tighter.
It almost never works. Here's why.
The Real Reason Toddlers Kick Off Their Blankets
It comes down to thermoregulation - the body's ability to regulate its own temperature. In adults, this system is well-developed. We kick off a blanket without waking up, or pull it back unconsciously.
Toddlers don't have that yet.
Their thermoregulation is still maturing, which means they're more sensitive to temperature changes and more reactive to them. When they get too warm under a blanket, their body's response is physical: kick, thrash, remove the source of heat. This often happens during the lighter stages of sleep which is also why it wakes them (and you) up.
The problem usually isn't that they don't want to be covered. It's that what's covering them is too warm or too heavy for their body to tolerate through the night.
Why Conventional Duvets Make It Worse
Most synthetic and down duvets trap heat. They're designed to create a warm pocket of air - which is great for adults in a cold room, but overwhelming for a small body that can't self-regulate effectively.
Signs your toddler's bedding might be too warm:
- Waking up sweaty (especially around the neck and back)
- Repeatedly kicking off covers within an hour of falling asleep
- Waking multiple times between midnight and 5am
- Red cheeks or warm skin when you check on them
What Actually Helps
The solution isn't a heavier blanket or a sleep training method. It's temperature-smart bedding.
Mulberry silk - like the fill used in alanunu duvets - works differently from synthetic or down. Silk is a natural protein fiber that responds to body temperature rather than room temperature. It releases excess heat when your child is warm, and retains warmth when they cool down.
The result: fewer temperature fluctuations through the night, fewer kicks, fewer wake-ups.
Practical Steps to Try Tonight
- Check room temperature - ideal for toddlers is 18–20°C (65–68°F)
- Reduce layers - if they're in a sleep sack plus a duvet, that's likely too much
- Switch fill material - from synthetic to natural (silk or lightweight wool)
- Go lighter, not heavier - counterintuitively, a lighter duvet with better temperature regulation outperforms a heavy one
When to Worry
Occasional blanket kicking is completely normal. If your toddler is waking every 1–2 hours consistently and appears uncomfortable (not just alert), it's worth ruling out the sleep environment before assuming it's a behavioral issue.
The 2am re-covering mission is exhausting. But it's often solvable - without a new sleep method.
