When you hear the adage "Charity begins at home", that covers teaching your children how to understand and speak your dialect as well. I spoke with a parent recently and he was of the opinion that there wasn't any need for him to be the one to teach his daughter his language as she would learn from school, whenever she starts school. Sigh
How is a child to learn his or her dialect in school rather than at home where family and friends visit and speak this same language? English is the official language in Nigeria
I remember my dad preventing us from speaking Yoruba as much as we would have loved to. As a matter of fact, up till this day I feel more comfortable discussing with my dad in English rather than in Yoruba. We would wake up and see both our parents and go "Daddy, good morning. Mummy, ekaaro". I still do it till today. Back then, my daddy would throw big English words at me and ask me what they meant. Maybe that also helped my accurate and mostly impeccable English knowledge and perhaps that's where my love for English language stemmed from.
I am very grateful my mum kept us grounded with our dialect.I could understand Yoruba very well but I struggled with speaking it as well as others did and it affected me when I got into Secondary School. I was teased and even bullied for my "oyinbo-ness", and it was really tough for me to fit in at times. Being the determined pikin I am, I started re-learning and perfecting the Yoruba language to prove that I was as Nigerian as those who could speak the language fluently.
In conclusion, I would recommend that every parent teach their children to understand at least one Nigerian language. There's no shame in it because it will help prevent your dialect from going into extinction and it would help stop your children from being bullied when they come of age and head out for higher education.
