Love to Dream Swaddle Up Baby Sleep Sack, Size S (8–13 lb) Oatmeal — 1.0 TOG Arms-Up Comfort

Love to Dream Swaddle Up size S is a 1.0 TOG arms-up newborn sleep sack designed for babies 8–13 lbs (up to 62 cm), offering a snug shoulder fit that keeps hips free and supports natural self-soothing.

Built around the brand’s award-winning ARMS UP shape, this oatmeal-colored sleep sack swaps loose blankets for a lightweight cotton cover that helps babies sleep in their preferred arms-up position. The size S fit (8–13 lbs, up to 62 cm / 25 in) prevents fabric from riding up over the face while leaving room at the hips for healthy movement. With a 1.0 TOG rating the Swaddle Up is intended for moderate room temperatures (about 68–75°F) and works with layers underneath to fine-tune comfort.

How does the ARMS UP design support a baby’s natural sleep behavior?

The Swaddle Up keeps a baby’s shoulders gently snug while allowing arms to stay elevated, which mirrors many infants’ instinctive sleeping posture. This open-arm position lets little hands reach the mouth for self-soothing without the restriction of traditional swaddles.

• Keeps shoulders secure while allowing arm movement for comfort.
• Permits hands-to-mouth access for independent settling.
• Reduces the need for re-swaddling as babies wriggle or startle.

Is the size S the right fit for my newborn, and why does correct sizing matter?

Choose size S for infants weighing between 8 and 13 pounds and up to roughly 62 cm (25 in). A correct fit prevents excess fabric from covering the face, keeps the swaddle anchored at the shoulders, and helps maintain a consistent sleep environment.

• Designed specifically for 8–13 lbs to limit fabric creep and returns.
• Snug at the shoulders while hips remain free for healthy movement.
• Tap the size chart on the product page to confirm weight and length before ordering.

How simple is it to use and manage during nighttime diaper changes?

Swaddle Up is built for practical nighttime use: a two-way zipper runs the length of the sack so diaper changes are fast and less disruptive. There’s no velcro or fiddly fasteners, which makes it easier for all caregivers to put the sleep sack on and off without waking the baby more than necessary.

• One twin zipper for quick diaper access and simple dressing.
• No scratchy velcro or multiple snaps to fumble with in the dark.
• Easy for parents, grandparents, or carers to use confidently.

What materials and temperature guidance should I consider?

The Swaddle Up in size S is made from soft cotton to be gentle on newborn skin and breathable for overnight comfort. With a 1.0 TOG rating it’s intended for moderate room temperatures—layer a bodysuit underneath in cooler rooms and reduce layers if it’s warmer.

• Cotton fabric for softness and breathability against delicate skin.
• 1.0 TOG suitable for room temperatures around 68–75°F (20–24°C).
• Layering recommendations: add or remove base layers to regulate baby’s warmth.

Who is this for? The Love to Dream Swaddle Up size S is ideal for newborns and smaller infants who prefer sleeping with arms up, parents who want a straightforward, low-fuss swaddle solution, and caregivers aiming to replace loose blankets with a temperature-appropriate sleep sack. It’s particularly useful for families seeking a reliable night-time product that balances security at the shoulders with freedom at the hips, quick diaper access, and breathable cotton for sensitive skin.
