Gaining weight!

Went to the dietician today. Will weighed 16 pounds 5 ounces. He had gained 5 ounces in one month, our goal was 8 ounces. We are now going to add something called duocal to his formula. Normal formula has 20 calories per ounce. We add a half of scoop more of formula to every four ounce bottle making each ounce 24 calories. By adding the duocal we are going to make each ounce 30 calories which should get him gaining. The dietician would like Will to be up to 18 pounds, that is our goal. By getting him up to 18 pounds he would be in the 50 percential for weight and height on the RTS growth chart (RTSweeties have their very own growth charts!). We go back in a month to check his weight again.
