You can use this from day one without any complicated wrapping, tying, or inserts. Its simple design is easy to use, secure and very soft. It is so nice to be able to have a little more freedom in the early days when your baby wants to be held all the time (and you want them close) but they’re sleeping a ton and you have things to do. My favorite wintertime hack is putting the carrier underneath a winter coat to keep your little one nice and warm. Using a carrier is also a great way to help prevent flat spots by getting your newborn off their back and letting them nap on you. This one is so easy to unfasten you can even attempt to make “the transfer” (the holy grail of moving your napping baby from your body to their crib) without waking. This is probably my most used baby item in the fourth trimester.
