Like so many of the other posters, I first have to thank you SO much for the MB!! It has been such a godsend for our son, Evan. Evan was a BIG boy when he was born (9 1/2 pounds!) and no matter how we swaddled him, he always pulled a Houdini and escaped almost as soon as we put him to sleep. His little arms and legs were always going a mile a minute, but since getting the MB, his sleeping habits have been amazing and he goes to sleep without any problems what-so-ever.
