I’ve been swaddling my baby since she was four weeks old, and she began sleeping in six hour stretches at night once she was swaddled with the MB. She now calms down immediately at the sight of the blanket, because she knows it means she’s about to get a good night’s rest. I don’t plan on discontinuing swaddling any time soon, but she is on the verge of outgrowing the blanket. I would love a larger size blanket!
