Happiest Baby Sleepea 5-Second Swaddle - 100% Organic Cotton Baby Swaddle Blanket - Doctor Designed Promotes Healthy Hip Development (Midnight Planets, Medium)

Meet the Happiest Baby Sleepea 5-Second Swaddle

The Sleepea 5-Second Swaddle was designed by pediatrician Dr. Harvey Karp and has earned recognition from The New York Times as a top swaddle option. In Midnight Planets, Medium, this wrap surrounds your baby with a 100% organic cotton shell and thoughtful details that support comfortable, secure sleep and hip-friendly positioning as little ones grow. The design aims to feel like a familiar, comforting hug that some families notice during late-night routines.

Premium Organic Comfort

The outer layer uses 100% organic cotton—soft to the touch and gentle on delicate skin. The fabric breathes with each breath, helping your baby stay comfortable without overheating. For families, the breathable weave can contribute to a calmer environment during naps and night sleep.

• Quiet, escape-proof Velcro keeps the wrap secure with minimal noise during late-night changes.
• Two-way zipper opens from the top or bottom for quick diaper access at night or during midnight changes.

Sleep Support and Transitional Use

The inner flaps cradle baby in a womb-like hug, and arm openings can unsnap for an arms-out option as your baby grows. This makes Sleepea a practical stepping-stone toward independent sleep. If your little one is just learning to move, the snug interior can feel reassuring, while the arms-out option invites growing curiosity without losing security.

• The 5-Second Swaddle design emphasizes fast, simple wrapping that some babies respond to with longer sleep periods.
• Breathable mesh across shoulders and legs promotes airflow and helps keep your baby comfortable during sleep.

Usage Note

Sleepea is not designed for use in a SNOO Smart Sleeper; if you’re using SNOO, the appropriate SNOO Sack is recommended.
