A slow-moving young child in the morning is almost always a biology story, not a behavior story. Sleep inertia, the groggy, disoriented feeling that follows waking, is real and physiological. Young children need time to transition from sleep to full alertness, and the speed of that transition varies by child. Rushing the transition does not shorten it. It just adds stress to it.
Good morning. Take your time waking up. I am going to get your breakfast ready.
