There are two styles in the swaddle – with baby’s arms down towards their body bending at the elbow, and the new arms down swaddle. The romper currently is available in the bent elbow style. Angus likes to hold his hands together so the bent elbow style suits him well. Reuben preferred being arms down completely so the new swaddle style would have suited him. I think the romper will be great for our plane trip as he can be awake and playing in it while staying warm, and then zip those arms and ready for bed. Two way zip on the swaddle ensures easy nappy changes. It is best to size up, as the arms themselves are quite narrow due to the zip taking up some of the arm space. New products including organic sleeping bags are being added to the range shortly so keep an eye out.
