This is another product we just gave away in our 'Ultimate Sleep Routine' contest. This is a super-snug sleep sack/swaddler that looks like it would be a great alternative to a regular swaddling blanket.
The thing we liked so much about the Miracle Blanket was that it was virtually escape-proof, and helped our son feel snug and secure while also preventing him from swatting himself in the face with a stray arm. Having never used the Woombie, my only hesitation is that I wonder if not having the arms secured against baby's sides would work for an extremely fussy or colicky baby.
In any case, I would definitely give this a try if you're looking for a swaddler, or as a transition between the miracle blanket and a regular blanket.
