We put ds in those swaddle things and he is fine we just got him one in a bigger size anyway so he could use it longer

I've seen the ready-made-swaddle style blankets that I think you're talking about and they give a bit more around the legs and hips too. The style I was taught in the hospital was just with a blanket and held tight around the arms, legs and hips so DD couldn't really move them, giving her the "security" of the same feeling as she had whilst in the womb.
