Velcro, zipper, or arms-up — which swaddle style is best?

There is no consensus winner. Velcro/hook-and-loop styles (HALO, Comfy Cubs) are the easiest to size to a specific baby; zipper swaddles are quieter for night changes; arms-up designs like Love to Dream work best for babies who fight having their arms pinned. Many parents in r/NewParents and r/newborns end up owning two styles.
