Description

The Love to Dream Swaddle UP 50/50 is designed to transition your baby from swaddled sleeping to arms-free sleeping. Parents know that swaddling their newborns is important. Babies between two to three months grow fast, and when they are able to roll over or show signs that their startle reflex has diminished, they are ready to be transitioned from swaddling to arms-free sleeping. But this transition can sometimes be hard because babies may still have some startle reflex present and they are used to being swaddled. The Love to Dream team designed the Swaddle UP 50/50 which is Stage 2 in Love to Dreams 3 Stage Sleep System - to make this transition easy for both baby and parents. The Swaddle UP 50/50 shares the same features as the Swaddle UP Original, but with the added versatility of patented zip-off wings. The Swaddle UP 50/50 will gently transition your baby from sleeping snuggly swaddled towards having the independence of sleeping with his or her arms free. The zipper design makes it easy to go back to the original swaddle design if your baby is not ready to transition. Once your little one is comfortable with both wings removed, the Swaddle UP 50/50 can be used like a snug and comfy wearable blanket, but with baby still feeling swaddled. Since 2008, Love to Dream has been finding simple, yet genius solutions to everyday parenting and baby needs. Our desire was always to create products that looked great and more importantly provided a solution to a parenting challenge. The best news of all is that our products work! So everyone in the family will achieve a better nights sleep. Functionality, usefulness and innovation are key for Love to Dream. It is vital that we offer products to parents (just like us) that will make their lives simpler and less stressful.

Feature

The Omni swaddle Sack with adjustable wrap and Sleeves with mitten cuffs is the ideal swaddle. The convertible design supports more sleep positions for baby's hands and arms, and provides parents with more options when preparing baby for safe sleep.
Arms up sleeves with mitten cuffs. The sleeves with mitten cuffs keep baby's arms warm and parents do not need to dress baby in a bodysuit. Less layers reduces risk of overheating. Integrated sleeves means less laundry for new parents.
Babies who can self-soothe sleep longer and better. When baby is swaddled with hands up or arms up, baby can self-soothe by sucking on hands. The integrated sleeves keep baby's arms warm.
Ergonomic design with 2-way zipper is easy to use. The wrap is narrow and does not interfere with baby's hips. The zipper allows parents to easily change baby's diaper by unzipping from bottom and easily place baby in the sack by unzipping from top.
100% premium cotton knit is breathable. Small 6-14 lbs, 0-3m. When baby is over 3 months, the AAP recommends parents to stop restraining baby's arms with a swaddle, and at 3 months, We recommend a transitional swaddle Sack or a wearable blanket for sleep.
