Hug Technology gently cradles your baby to help settle the Moro reflex and active sleep. The snug, seamless knit echoes your caring embrace so your little one can self-soothe and drift back to sleep more easily.
As your child starts to roll, the swaddle transitions into a wearable blanket. Simply leave their arms out for safe, comfortable movement, so one piece supports the newborn stage and beyond.
Built in line with AAP guidance, the fit is secure around the chest and comfortably loose around the hips for healthy movement. The easy access diaper flap means quick nighttime changes without unwrapping.
A few simple factors help you pick a swaddle that fits well and keeps your baby safe and comfortable.
- Get the size right: Size small suits 6 to 12 pounds and works well if you are still expecting. Choose large for babies already over 10 pounds, roughly 12 to 18 pounds.
- Look for a safe fit: A good swaddle is snug around the chest but loose around the hips to support healthy hip movement. Avoid anything that feels tight at the legs.
- Plan for rolling: Once your baby shows signs of rolling, switch to an arms-out style. A design that converts to a wearable blanket saves you from buying twice.
- Match warmth to the room: Use the room temperature to decide how many layers to put underneath. Warmer rooms need fewer layers so baby does not overheat.
- Choose easy nighttime access: A diaper flap or easy opening lets you change baby quickly without full unwrapping, which keeps everyone calmer at 3 a.m.
What size should I order?
Choose small for 6 to 12 pounds, which is ideal if you are still expecting. If your baby is already here and over 10 pounds, order the large, which fits roughly 12 to 18 pounds.
Is this safe once my baby starts rolling?
Yes, it transitions into a wearable blanket. Once your baby shows signs of rolling, simply leave their arms out so they can move freely and safely.
How is this different from a traditional swaddle?
It uses a slip-on, seamless knit design, so there is no wrapping or re-wrapping. It stays in place through the night and will not unravel the way wrapped swaddles can.
How do I dress my baby underneath it?
Match layers to your room temperature. In cooler rooms add layers underneath, and in warmer rooms use fewer or none so your baby stays comfortable and does not overheat.
Can I change a diaper without taking it off?
Yes. An easy access diaper flap lets you handle changes quickly without fully unwrapping your baby, which helps keep nighttime changes calm.
