Ok, I am super frustrated. I just wrote the long post and it deleted itself, go figure.
I was just writing about Nolan and is lack of gaining weight. He has dropped to below the 5th percentile for his weight and the 20th for his height. After receiving some information and doing some research I think it is a Gluten allergy (otherwise known as: Celiac). I am going to track what he eats and his poop for a couple days to see if there is a relation. Sounds like fun I know. If there is a correlation I am going have the doctor run some tests. I'll update the information once I find out more.
