The Best Baby Swaddles

Swaddling—wrapping a baby securely in a thin blanket—can help minimize the startle reflex, replicate the coziness of the womb, and calm a baby who’s overstimulated. To find the best swaddles, we had five families spend two weeks testing 11 of them with babies ranging in age from 2 to 12 weeks, and talked to four birth and postpartum experts. There’s no single swaddle that will work for every baby, and the right swaddle for one baby might even change between the newborn stage and later months. Still, we found that the Happiest Baby Sleepea is the most effective at keeping a baby securely wrapped, is among the easiest for parents to use, and is safe and comfortable for the baby.
