Query: DO NOT USE!!!

I use to be a big fan of the Halo sleep sack...until I found my baby with the swaddle bundled around his face and neck!!!! Yes I did use the velcro tabs to supposedly hold the swaddle piece down, but they are not strong enough if my son can undo them in his sleep (he was sound asleep when I found him).Please please do not use these!!!
