My daughter Cassidy was 16 months old and still in diapers when we started to suspect that something wasn’t quite right. My husband and I didn’t know what to do or think, but we knew something was wrong. Cassidy was an early talker, and each morning we found her standing up in her crib telling us “Cassidy thirsty.” She kept drinking and drinking—and she was very hungry, too. She kept wetting through her diapers, clothes and bed sheets. Deeply concerned, we took her into the pediatrician three weeks in a row. Our regular doctor happened to be on medical leave during this time, so we saw other doctors who weren’t as familiar with her history. At one appointment, she was diagnosed with an ear infection. At others, we came home without any diagnosis. No one asked specifically about her symptoms of increased urine and thirst, and while we thought we were communicating effectively, perhaps we weren’t. As first-time parents with no experience in the medical field, we were quick to chalk it up to our own inexperience.
