This sleep positioner was something I wish I knew about a very long time ago. My son had projectile vomitting and acid relfex. He had to sleep in his bouncer for the longest time. This product helped with the acid reflex. It does it's purpose. I wouldn't say this is a MUST have, but it is a product that I would look into if your deciding to get a sleep positioner, or trying to prevent flat head, or to help with acid reflex in babies. It's softer, and seems much more comfortable then other sleep positioners on the market. I traded a cheap one for this one, and would never go back. I will buy this product again to use with future children. I also tell friends and family about this product and to buy it if they need a sleep positioner.
