My son is three days shy of six weeks. From his first week home he has HATED being swaddled. He's escaped from it in five minutes flat, no matter how tight I tuck it, or who does the tucking. I even tried an escape proof swaddle which only served to royally piss him off and keep him from sleeping more than an hour at a time. The first night I put him in this..he slept straight through 3 to 4 hours at a time before waking me for a bottle. I want MORE of these. They do the job I need them to, my son likes them and most of all MOMMY GETS SOME SLEEP!
