I've got two kids, and I tried swaddling for both. The older loved it, he calmed down as soon as he was put on the blanket. He was a bit colicky, and the swaddle calmed him right down. We kept him swaddled for the first three months (with frequent diaper changes!), and then he got active and didn't need it anymore. The younger was ok with it for the first week, and and then flat-out refused to cooperate, so we stopped and she was happy. I'm glad to say that they're both doing fine.

As for the baby in the video, it's obviously older than three months and used to being unconfined. Of course it wouldn't be happy with the whole proceedings. Also, the blanket used was far too small for a good wrap, and the technique was sketchy.

I'd recommend for any new parents to try swaddling - if you have a fussy baby, it can be a life-saver! Just use common sense, pay attention to your child, and remember that every child is unique! Happy parenting!
