i think at that weight and age, even if the bag overstates the amount you are supposed to give them, it would not hurt to feed them that much....they are still growing and playing lots and need their nutrition and energy...i do not think you would want to "limit" their food until after they turn 1 year...i have always fed more than the manufacturer "recommends" to my kids and NONE of them are overweight at all
