Yes, praise be to the swaddle-o-matic. I am totally swaddling challenged, and DH bought me two from Kiddopotamus. They saved us (and probably Liam) for a couple of weeks. Plus, one is green, so- with his hair that sticks up out of it- he looks like a caterpiller. I started calling him my very hungry caterpiller and reciting the Carle book to him while I bundled him up.
I think Mr. Liam is beginning to outgrow his already. Or else the velcro is failing. He can fight his way out of it now, and the power of the swaddling seems to have less power over him.
