What's up with Tristan?

I realised that some blog readers might not understand why I'm tracking Tristan's eating habits. For the past 3 years or so Tristan has been "off the charts" for growth, on the low end not the high end. He is very small for his age, proportional, height and weight match, just very small. He also has a few developmental issues such as learning basic things at a later age than typical and acting immature and seems to have low endurance at times. When he was small he had some issues that resolved (soft spot seeming to close early and a couple others). He also turned out to have fairly poor vision. Since he is still not growing well we are investigating if there is some other health problem (s) causing the poor growth. There is nothing that jumps out to suggest anything major is wrong but several smaller things. Tracking his food intake is just a way for me to see if there are any patterns. Tristan is definitely a lover of junk food in our otherwise healthy family! He also dislikes some foods due to the way they "feel" in his mouth.

That's about it right now, he'll have some more tests later this week.
