These blankets are the greatest! The drug babies we get have a high pitched scream and shake as they go through withdrawals, and these blankets keep them so much calmer. The blanket helps keep their fussiness under control. I did a presentation in our county and demonstrated how to wrap the baby; The sweet little baby I had fell asleep just as I finished wrapping him and lifted him up to show him to everyone! I have always swaddled my babies, and these blankets never come unwrapped.
