Mouths of Babes Department

Our youngest child, Petachya, aged 4 and a half, often has trouble getting himself downstairs in the morning. Rena will wake him up, make sure that he's awake, get his clothes set for him, and then move on to other things. I frequently arrive home from shul to find him slowly moving down the steps a half-hour later.
We're trying several remedies: a check system (not really working), taking away his DS time (working a little), positive encouragement (makes him feel good but also doesn't work).
Today we had the following conversation.
Me: Petachya, you can't read in the morning. You have to get dressed.
P: I'm not reading.
Me: Well, you can't just stand around looking at things.
P: I'm not looking at things.
Me: Then what are you doing for all this time?
P: I'm lying in bed.
Stupid, he's not.
