My daughter is 15 months old and has been excessively thirsty. But oddly she is not urinating very much. Plus she has gone from being a very good sleeper, to hardly sleepy at all. This has been going on for about 3 months now. Any ideas as to what this can be? I'm very concerned for her. My gut feeling tells me that something is wrong.
