Is he healthy, active,happy?? If so, don't worry about it...eating habits change as growth spurts come and go...as activity levels change...let him eat until he is done and then let him move on. A lot of times toddlers and older infants prefer to "graze" ....just eat a little here and there...actually it is a good thing because it helps keep their blood sugar levels more even and avoids those mood swings!!!
