Done safely, swaddling can soothe newborns: keep it firm across the chest but loose around the hips (to protect hip development), never cover the face, and always place a swaddled baby on their back. Stop swaddling as soon as your baby shows any sign of rolling, usually around 8 weeks to 4 months.
Glossary
Swaddling
Swaddling is wrapping a young baby snugly in a thin blanket to limit the startle reflex and help them feel secure for sleep.
