Hi guys, I'm after some advice. My 8 year old son is very skinny (can see all bones), his skin is pale and he looks dark under the eyes. He wears the same size clothes as his 4yo sister. He's also cranky and tired and cries at the drop of a hat. He has had trouble focusing at school as well. I took him to the dr a couple of months ago and he was in the low percentile for weight and height. We had to keep an eye on his food intake and take him back to the dr to see if there was an improvement. I took him back today and he hasn't put on much weight so dr took some blood and are going to run some tests. Has anyone else's child had these symptoms and what did it turn out to be?
