It is tricky to get swaddling with a blanket right – it can’t be too tight and it can’t be too loose or it will come undone. This is where our Swaddle to Sleep Bag comes in handy. The sleeves on our sleep bag popper shut so baby’s arms can be safely tucked inside giving the same benefits of swaddling, without all the fuss. It is impossible to know whether any baby will prefer to be swaddled or not, that’s why our sleep bag gives you the option. The poppered sleeves also provide the ability for baby to gradually grow out of swaddling by allowing one arm to be swaddles and one arm out, then eventually, both arms out.
