Grandfather, what's wrong with you?

I first learnt this song when I was in school primary school, while we were learning about our bodies.

Batswana mothers also sing the song to put their babies to sleep, and I was no different when Baby was small. Dont know if the song was originally in Setswana, or if it's a translation.

Ntatemogolo o tswa kae kajeno
Ke tswa kwa sepetlele godimo ga thaba
O bolaiwa ke eng?
Ke tlhogo, magetla, sehuba le letheka
Mangwele le menwana
Mangwele le menwana

O bolaiwa ke eng?
Ke tlhogo, magetla, sehuba le letheka
Mangwele le menwana
Mangwele le menwana
