Query: Good but missing one important feature

I love the Sleep sacs by Halo. My daughter lives in them. i feel safe with her in them. The only feature i thought this one had was the Velcro arm holes. The one we received from the Hospital had that feature and we love it! But unfortunately this one did not. So we do struggle to get her arms through the arm holes and it can be annoying. Besides that i would recommend this product.
