When do the molars start appearing? My boy is 15 months and no molars yet.

According to this article, the molars are supposed to erupt in months 10 to 14. However, as each baby develops at a different pace, you don't need to be overly worried. http://sg.theasianparent.com/the-go-to-guide-for-your-babys-teething/

The first molar should erupt between 13-19months and thus you do not have to worry.

thanks
