Our patented Hug Technology gently mimics a parent's embrace to calm the Moro startle reflex. That steady, secure feeling helps babies settle faster and stay asleep longer.
The 3D stretch knit breathes from every angle with a lightweight 0.2 to 0.3 TOG rating. Your baby stays cozy without overheating, night after night.
When your baby starts rolling, the sack converts into a wearable blanket by leaving the arms out. One piece supports safe sleep from newborn through toddler.
A good swaddle keeps your baby secure and safe while fitting the season and their stage.
- Check the fit: Look for snug support around the chest and room to move at the hips. This protects healthy hip development while still calming the startle reflex.
- Match the TOG to your room: A lightweight TOG around 0.2 to 0.3 suits most rooms year round. Pair it with the right layers underneath rather than a heavier swaddle.
- Plan for the rolling stage: Choose a design that converts to arms-out use, so you can keep using it safely once your baby starts to roll.
- Prioritize breathability: Breathable knit fabrics help prevent overheating, which matters most for overnight sleep.
- Think about diaper access: A bottom opening makes late-night changes far easier and keeps your baby more settled.
When should I stop using the swaddle with arms in?
Once your baby shows signs of rolling, switch to arms out. This sack converts to a wearable blanket so you can keep using it safely through that transition.
Is it warm enough for winter or too warm for summer?
It is a lightweight, all-season design at 0.2 to 0.3 TOG. Adjust the clothing layers underneath to keep your baby comfortable in any room temperature.
How do I change a diaper without waking my baby?
The bottom flap opens for diaper access, so you can change your baby overnight without fully unwrapping them.
Can I machine wash it?
Yes, it is machine washable. The seamless 3D knit holds its stretch and shape through regular washing.
What size or age is this made for?
It is designed for newborns through the rolling stage, adapting to your baby's natural movement as they grow.
How does shipping and returns work?
We ship from a US warehouse with free US shipping on orders over $100, and we offer 30-day returns. Our human support team is happy to help if you have questions.
