Happiest Baby Sleepea 5-Second Swaddle – 100% Organic Cotton, Doctor-Designed for Healthy Hip Development | Ivory Planets (Medium)

Overview

Happiest Baby Sleepea 5-Second Swaddle in Ivory Planets, Medium, offers a soft, safe wrap crafted from 100% organic cotton. Designed by pediatrician Dr. Harvey Karp and refined with input from sleep experts, this swaddle carries the International Hip Dysplasia Institute seal of approval. The combination of premium fabric and thoughtful fasteners creates a snug, womb-like feeling that can help babies settle more easily and stay comfortable through the night.

The Sleepea focuses on hip-friendly positioning, escape-proof security, and practical access for nightly changes. With a quiet Velcro system and a 2-way zipper that can open from the top or bottom, caregivers gain flexibility without disturbing baby’s sleep. Inner flaps deliver a secure embrace, while arm openings can unsnap to ease transitions from full swaddling to arms-out sleep as your infant grows. A breathable mesh at the shoulders and legs enhances airflow where little ones tend to overheat.

Key features

• 100% organic cotton delivers a soft, breathable touch for baby's skin
• Extra-quiet Velcro keeps the wrap secure without noisy disturbances
• Two-way zipper opens from the top or bottom for simple midnight diaper changes
• Inner flaps provide a snug embrace that helps minimize startles
• Arm openings can unsnap for arms-out sleep transitions as baby grows
• Breathable mesh at shoulders and legs helps prevent overheating
• Hip-friendly design supports comfortable hip positioning

Usage and routine

Many families notice fewer startles and longer stretches between feeds, thanks to a secure, womb-like feel. Sleepea serves as a gentle stepping stone for those exploring independent sleep patterns, especially during the transition from full-body swaddling to arms-out sleep as mobility develops.

Note: Sleepea is not designed for use with the SNOO Smart Sleeper and should not replace the SNOO Sack in that setup.

Care and safety tips

Follow the care label to maintain softness and fit. Keep the wrap snug but comfortable, and ensure the shoulder area remains breathable for optimal airflow.

Usage tips

• Ensure the wrap is snug yet comfortable around the chest and hips
• Use arms-in for early weeks, then transition to arms-out as comfort grows
• Pair with a safe sleep environment and a consistent bedtime routine
