Lia will turn three on December 28th. She doesn't walk independently – she crawls a lot, of course – but she's close to it, and although she communicates in her own way – she points and makes herself understood – she still doesn't speak beyond a few words. She's had multiple tests, and she's being monitored by specialists of all kinds, but they still haven't found the disease that explains the causes of this global developmental delay, although they suspect it could be a rare disease of genetic origin, explains her mother, Laura López Crespo, 39.
