I'd put it down to teething. Some kiddos get upset tummies from all the drool. Mine would also eat constantly, and wake in the night during growth spurts. Once they slowed down, I'd be wondering why they were eating so little.
But I agree, ask a pediatrician. Last year, my then seven-year-old was just acting "off". Cranky, not sleeping, doing poorly in school, but not sick. When I took him to the doctor, he was diagnosed with a raging sinus infection. His only symptom was crankiness and trouble sleeping.
