Emily was not dx'ed until she was 7, so anything about her health when she was little we cannot be completely certain of. But I think she went through a big change when she was about 3. Her weight and height were about 65/80% on the charts, she'd always maintained that consistent curve from infancy till age 3; she was even chunky as a baby! ...and then she just flatlined on the charts and she was in the 5th% for wt/ht by the time she was dx'ed. During that time, she never stopped eating- as a matter of fact, as time went on, the hungrier she got. Now, if she was dx'ed earlier, I don't think she would have dropped off so much on the charts (we would have had the chance to start enzymes), but that was when things changed for her.
