IDK, it looks like maybe he's eating watermelon and maybe it's just color reflecting? To me it looks like another 'look, I'm eating' picture. Note the cereal box prominently displayed in the background.
In one it appears 2 year old Sky is taking/getting a bath in the kitchen sink. And .. is that a full plate of some sort of meat with sauce on it to the left of the sink? :waitasec:
Hmmm. Maybe it's because Sky just ate so now he must get clean ... immediately?
ETA: No, I take that back, it does look like his chin and cheek are red, and the fruit looks too far to cause color reflection (to me.) But now I wonder if that's a tomato..
