So the Pictures below are of my little buddy. He is now 4 months old. He weighs 13lbs 3 oz in the 25% and 25 inches which is the 75 %. So yes is is a skinny tall boy. Not like his brother who they were telling me to control the flow that he was getting too big too fast and with Brix they are saying I may need to supplement. I dont know what to think although I do believe if he was starving he wouldnt be the good baby that he is... He is a really happy layed back baby. (unless his brother is beating on him :)
