Love to Dream Swaddle UP Transition Bag ($40)
Some babies have a hard time transitioning from the wrapped-up comfort of a swaddle to an arms-free sleep sack, which is where this transition bag comes in. The "wings" on either side come off to let baby's arms free. When you're transitioning to a sleep sack, the brand recommends starting with just one arm free to get your baby used to the sensation. After a couple nights, let loose the other one, too.
It won't work for all babies, but the ones who love it really love it. "The materials are soft and warm, and a really useful guide of what to wear is on the back of the packaging," one reviewer said. "There is a transition period for your little one as you can zip off each handcuff to get them ready for a sleeping bag. Since moving our little one into these, he's slept far longer than before and doesn't startle himself awake, and we've even managed to get some better sleep ourselves as parents."
