Katie's urine test indicates that she is digesting properly. If she doesn't pick up the pace on gaining weight during the next 6 weeks, we'll go back to the nutritionist. I think a lot of it is she burns as many calories as she takes in. She rarely leaves any formula in her bottle and she eats a lot at meal times. We're back to the issue of her tummy simply not being big enough. For now, we'll try to feed her higher calorie foods. More later!
