My 3yo seems to tire very easily. He doesn't last more than 10 or 15 minutes with most physical activities, even the really, really fun ones. I thought it was just his age, but most others his age are the energizer bunny. He also seems to get tired a lot more easily than his older brother did at that age.
He eats well. His weight is good. He appears strong and has good muscle definition for his age. He gets plenty of sleep.
Any thoughts or experiences?
