As a stay at home mother of 4 children, I can honestly say that the DockATot has been by far the best baby product I have ever bought. I am currently using the Deluxe DockATot for my 8 week old, baby Mikey. We have been using it since we arrived home from the hospital. When I put baby Mikey in his DockATot, I can visibly see him relax and begin to sooth himself to get ready to sleep. I also ordered the Grand size DockATot for his older brother, Max, who just had to try it out in his junior bed and now does not want to sleep without it.
