Fat, calories, and other things you usually avoid

Thanks everyone for reading and responding to my last post.  I know I didn't specifically ask for advice, but I appreciate those of you who gave it.  We really sat down and looked at the food Xavier was eating and decided he actually might not be getting enough calories/fat in his diet.  It was sort of a foreign thought to us.  We have been working on eating low calorie, low fat food as adults who need to lose/maintain weight and Xavier eats what we eat. So, even though he was eating yogurt, it was non-fat and so on and so on.  Yesterday was our weekly trip to the grocery store and J.J. got to accompany us because he is on Spring Break. Hooray!!  We had to really examine the food we bought.  Believe it or not it is somewhat difficult to find higher fat yet still nutritious foods.  I guess I need to research foods with "good" fat, but I didn't do that before grocery shopping.  We just tried to substitute some of our normal low-fat choices with the more normal fat kind.  Does that make any sense?  So I am going to try to give more attention to Xavier's diet and see how that goes.  He ate a whole Nutella to go snack during church last night, so that is a start.  I am still open to more advice in the weight gain vs keeping healthy foods on the plate issue.  I think they can be compatible if we work at it.  I'll keep you updated on our progress.  Happy eating everyone!
