If your baby passifies himself by putting his hands on his face, like my does, this product is not for you! From the womb my son enjoyed having his hands on his face and he is not able to calm himself without them. This product traps the babies arms underneath it. Whereas with a blanket, he can get his hands out if he needs them. Also, this blanket is hard to figure out, it does not multi-function like a blanket can, and once any baby becomes aware of their hands, they don't want them trapped anymore. I found the Halo Sleep Sacks to be a much nicer product!
