Buying Guide: Key Considerations For 18-Month-Old Sleep Sacks
- Material and skin sensitivity: Choose cotton for sensitive skin or bamboo-rayon blends for superior softness and temperature regulation.
- Tog rating: 0.5 to 1.0 suits moderate-to-cool climates; adjust with room temperature and layering.
- Fit and size: Ensure enough room for leg movement but not so loose that fabric can be kicked off.
- Closures: 2-way zippers ease night diaper changes; zipper guards protect delicate skin.
- Safety features: Look for necklines that prevent fabric bunching and safe sleep guidelines aligning with CPSC or similar standards.
- Care and durability: Repeated washing may affect fabric texture; select machine-washable options and follow care instructions.
- Longevity considerations: Some sacks cover up to 24 months or more; check sizing charts to avoid overgrowth too quickly.
