The Pippalily swaddler is designed to grow with the baby. Simply fold the top of the swaddler so it is in line with the baby's shoulders - fitting their individual size. As the child ages, and prefers access to their hands, you can simply swaddle one arm or leave both out.
We have specifically chosen a lovely light weight bamboo fabric as overheating is a factor for SIDS. Light weight fabric allows the parent to dress the baby appropriately for their environment, without the worry of a heavy swaddler.
