Can I leave my babies arms free while swaddling?

Although swaddling encourages tucking both arms in to avoid twitching and facial scratches from those sharp tiny nails, leaving one arm free might make your baby more comfortable. The hand-to-mouth reflex is a natural one that your baby is used to. Our blankets will still swaddle effectively if you leave one arm free for sucking although a regular blanket might come undone. You can leave both arms free, but it defeats the purpose and might mean that it is time to stop swaddling.
