I looked for a light for my toddler because when he was ready to be out of bed, he thought everyone should be too. My Tot Clock changes from blue (night) to yellow (day) at a preset time. It also has a wake up song if you want it. For gradual, I know that iHomes have a gradual wake up. I looked at a lot of the tot-type clocks when I settled on the one I did, and many didn't have great reviews. I'm very happy with the one we selected.
