Who are you?

This is what I want to say to my child: "Who are you and what have you done with Stone?" Why? Cause he's just been strange as of late. Nothing big, and I'm not worried, it's just been little things that have not been much to his character. For example, he ate some carrots the other day... what?!?! This is the child who won't even TRY something new and he was chomping on them like nobody's business. Not that I'm complaining or anything, (I was actually happy about it) but it just took me off-guard and I thought it a little strange.

Today for lunch, he ate a whole bag of chips, half a grilled cheese sandwich, juice, and then half a slice of strawberry pie. Bottomless pit, as he acted as though he still wanted to eat something after all that. He usually doesn't eat half of that at any one given time.

Then this afternoon, he slept for about 20 minutes and then woke up screaming. I then spent the next 30-40 minutes trying to calm him down, but to no avail. Finally, I got him to watch one of his favorite videos, which finally got him to stop screaming. What is that? (He's done this several times before, so this is not the first time.) I couldn't figure out if he was hurting (like a head-ache), had a bad dream, or something else entirely. After the video, guess what... wanted to eat again! (This is AFTER the fact that he had some milk right before the video). So, some fruit snacks, cheese puffs, and juice later, he STILL wanted to eat. I wouldn't let him, as it was getting close to dinner time. So, maybe a growth spurt? Any ideas?
