Buying Guide: Key Purchase Considerations

  • Safety and fit: Look for snug, secure fastenings and avoid loose fabric that could cover the face. Ensure proper arm positioning according to the baby’s preference.
  • Temperature and TOG: Choose TOG rating appropriate for the climate. Lighter TOG (0.5-0.8) for warm nights; higher TOG (1.5) for cooler evenings.
  • Transition readiness: If your baby starts to roll, select a transitional design that allows arm movement and gradual unwrapping.
  • Ease of use: Consider how easy it is to put on, adjust, and wash. Velcro, zippers, or snaps affect daily use.
  • Care and durability: Cotton fabrics are breathable and durable; check for washing instructions to maintain fit and color.
  • Breathability and movement: Favor fabrics that regulate moisture and heat to reduce overheating and skin irritation.
