Thank you for viewing. This is a LOVE TO DREAM Swaddle Up. I am selling it because my child has outgrown it. While it may vary from person to person, it was very helpful for us. When the baby wears this, they go into sleep mode, and if you make it a habit from the beginning, it can also lead to sleep training, so I recommend it. Brand: LOVE TO DREAM Color: Gray Design: Zippered Material: Cotton Size: M, for babies weighing 6-8.5kg Length: 64cm Fabric: 93% cotton, 7% elastane No pets, no smoking.
