I'm just going to go ahead and tell you that I have decided the DockATot is my favorite baby product of all time. I wish I had it with my first two. Our main use for it is sleeping at night. We started out with our Hattie girl sleeping in the middle of us with the DockATot in our bed. She slept well in it from day one, and there was no risk of one of us rolling over on her or pulling blankets up too high in our sleep. We all got better sleep because of it and we were sold right away. What a blessing. After a couple of months, we transitioned Hattie into a bassinet in our room, and we just put the DockATot right in her bassinet so there wasn't much of a difference for her. The transition to a crib one day will be so easy on her because of this. She naps well in it and we bring it with us when we travel too. It has truly been a life savor. I highly recommend this product.
