Query: Would be great...if not for the velcro

I love sleep sacks and feel great about my son's warmth and safety while wearing them. These from Kiddopotamus are soft and roomy, BUT there are two problems with the velcro closures on the shoulders: 1. Opening the velcro is LOUD and right next to little ears; and 2. It scratches his cheeks, no matter how we try to cover the roughest part. We got rid of the Kiddopotamus ones and found others that have worked better (especially the Lullabags, except that they run small).
