aden + anais Baby Sleeping Bag – 100% Cotton Muslin Wearable Swaddle (TOG 1.0, Large 12-18m)

Overview

The aden + anais Baby Sleeping Bag is a wearable blanket designed to replace loose blankets in the crib. Crafted from 100% cotton muslin, it delivers lightweight warmth with breathable comfort. The two-layer muslin feels soft against baby’s skin and improves airflow, while the sleeveless design helps keep little shoulders cool as they sleep. The roomy sack allows gentle kicking without uncovering the baby, helping you maintain a cozy, snug sleep environment without the need for loose blankets.

Why parents often choose this design

• Safe and cozy: a prewashed sleep sack creates a secure sleeping space by eliminating loose blankets in the crib.
• Breathable warmth: two light muslin layers promote airflow, reducing the chance of overheating during naps or night sleep.
• Simple diaper changes: bottom zipper design enables quick checks and diaper changes without fully waking the baby.
• Durable softness: muslin fibers soften with each wash and continue to hold their shape through many wears.

Material, care, and durability

The fabric is pure cotton muslin, chosen for its softness and gentle touch. With normal washing, the material becomes even more comfortable over time while maintaining its structure. This makes the sleep sack a practical option for everyday use, especially for families who prefer a reusable, eco-friendly solution.

Care tips: machine wash and tumble dry on low or air dry to preserve the fabric’s integrity. The durable weave resists pilling and keeps a fresh look wash after wash.

Sizing and fit

Sizing is designed to grow with your baby. Available ranges typically span from Small to X-Large, with corresponding weight and height guidelines to help you choose the best fit. The sack’s generous interior allows room for kicking while ensuring coverage over pajamas, reducing the need for extra blankets.

• Small: 10–18 lb, 23"–28"
• Medium: 15–24 lb, 26"–31"
• Large: 22"–28" lbs, 30"–34"

Usage tips and considerations

Use the sleep sack over regular sleepwear to create a consistent, comfortable sleep space. For nighttime diaper checks or changes, the bottom zipper provides easy access without fully waking your baby. If you live in cooler environments, consider layering to reach a comfortable TOG level as indicated by the product specs (TOG 1.0).
