Quick answer

To swaddle with a flannel receiving blanket, lay it flat in a diamond shape, fold down the top corner, place your baby on their back, and wrap each side snugly across their chest, tucking the bottom under their feet. Always leave room for hip movement and stop swaddling once your baby shows signs of rolling.

Why flannel works for swaddling

Flannel receiving blankets are a popular choice for swaddling because the soft, breathable cotton fabric helps regulate temperature and prevents overheating. The gentle stretch and weight of flannel also make it easier to create a snug wrap that stays in place through the night.

When to stop swaddling

Swaddling is only safe until your baby starts showing signs of rolling over, usually around 2 to 4 months. Once your baby can roll, stop swaddling to reduce the risk of suffocation. Also, never swaddle too tightly around the hips; allow room for natural leg movement to prevent hip dysplasia.

Step-by-step swaddling technique

  1. Lay the blanket in a diamond shape: Spread the flannel blanket on a flat surface with one corner pointing up. Fold the top corner down about 6 inches to create a straight edge for your baby's head. Ensure the folded edge is level with your baby's shoulders, not their neck.
  2. Position your baby on their back: Place your baby on the blanket with their head above the folded edge, shoulders just below it, and feet pointing toward the bottom corner. Always place your baby on their back for sleep, never on their side or stomach.
  3. Wrap the right side across: Take the right corner of the blanket and pull it across your baby's chest, tucking it snugly under their left arm and behind their back. Make sure the wrap is snug but not tight enough to restrict breathing or movement.
  4. Fold up the bottom: Bring the bottom corner up over your baby's feet and tuck it under the folded edge at their chest. Leave enough room for your baby's legs to bend and move freely. Never wrap the bottom too tightly; loose hips are essential for healthy hip development.
  5. Wrap the left side across: Take the left corner and pull it across your baby's chest, tucking the end securely under their back on the right side. Check that you can fit two fingers between the blanket and your baby's chest to ensure it's not too tight.
  6. Check for safety and comfort: Ensure the blanket is not too loose, and that your baby's face is uncovered. Confirm your baby's hips have room to move, and that the swaddle doesn't come undone during movement. Stop swaddling as soon as your baby shows signs of rolling over, usually around 2 to 4 months.
