In Kenya, the word for dad is baba.And the word for granddad is babu.
Sounds like baboon with the final 'n' missing. No comment!
Here I am in the grounds of Fyvie Castle. Revelling in both roles.
Babu to my oldest granddaughter.
Baba to my oldest daughter.
As baba to 6 and babu to 4 (and a half), I count myself blessed.
