What age should a child master the TH sound?
Most children master the voiceless /TH/ (as in "think") by age 5-7 and the voiced /TH/ (as in "this") by age 5-7 as well. It is common for children to substitute /F/ or /D/ for /TH/ during early development.

For the voiced /TH/ (as in "this"), do the same but turn your voice on — you should feel a vibration in your throat.
