Rocking, swaddling, and white noise: a new way to soothe babies after heart surgery?

This study looks at whether a multifunctional baby carrier that rocks, swaddles, and plays white noise can help infants (0-3 months old) feel less pain, sleep better, and have steadier heart rates and oxygen levels after congenital heart surgery. About 52 babies will be randomly assigned to use the carrier or standard care. The goal is to find a gentle, non-drug way to support recovery in the intensive care unit.
