It was sometime early this year that we discovered that he has a strand of grey hair. It wasn't causing any concern as we thought that it was just that ONE and ONLY strand. We found a strand or two appearing as time goes.
Just last week, I saw about 3 or 4 strands hair with greying ends. At closer look, they are quite noticeable. The greying portions seem to grow at the ends first. W's daddy is concerned and pestered that I take him to our padietrician. Yeah, I'll definitely take him to get an expert's advice.
To jump to conclusion, thoughts such as malnutrition or abnormality crossed our mind.
