Ning Ning begins to teethe on 3 March 08 (when she was 9.5 months old). We manage to find this Baby Tooth Chart from http://anbesol.com/baby/chart.asp which can update and record the teething process / development.

Based on this Chart, Ning Ning is a bit slow in the teething process but it is still alright. When she bites us, we can feel the pain compare to before.
