doctors doctors doctors jackson is so sick of doctors

So we went to our new pediatric doctor. Jackson had his one year shots and I was concerned about his weight and having constant diarhea. JACKSON WEIGHTS 16POUNDS 2OUNCES! He hasn't gain any weight in the last like 4 months. I knew he wasn't gaining much but it really stuck me when I got back form Mexico, just how fragile he looked. He's had really bad diarhea since November. Which the doctors' thought was just from all the antibiotics he's been on since November, but now they're not so sure . He's having tests done (we had to give blood, urine and like 8 poo poo samples.) I don't know exactly what they're looking for. Something to do with his body not absorbing vitamins, allergies, or maybe he caught something by taking so many antibiotic that is messing up his digestive system. I also have to go see a G.I. which I think stand for Gastric Intestinal specialist.
