We love it. The cocoon certe expensive but we used everywhere during the first 4 months. He slept in the night, the day in the living room with us, we carried away with as the travel cot (at this age not need cot ...) I do not know if c is binding but baby has never had a problem of ebbings he made his nights of the 2nd month and sy felt very well. In short he was using 200% of its capabilities and recommend it to everyone who's wondering about its usefulness.
