Zipadee zip transition swaddle by sleeping baby. This is size small, designed for babies 4-8 months or 12-19lbs. It is light blue with helicopters and clouds and made of 100% cotton. It’s in excellent condition - no rips or stains. This sleep sack is designed to help transition baby out of a swaddle once they have learned to roll over. The starfish design allows some movement of the arms so that it is safe even if baby rolls over, but the sewn sleeps still apply some pressure to make baby feel held and safe. There is plenty of leg room to allow baby to kick and move.
