I've not used the Miracle Blanket, but after receiving advice about calming down my fussy baby through a request here, I SWEAR by swaddling my baby when he gets wound up and for bedtime. I use a Kiddopotamus SwaddleMe wrap and he is soothed within minutes. It's literally saved my sanity, not to mention has allowed my 4 1/2 week old son to get on a 'sleep schedule' for night time (eat around 10, sleep til 2 and eat again, sleep til 6 and eat again), which is something I can totally deal with!
