Was in a bus heading to Ikeja, was just having fun on my smartphone when this lady came in with her baby (1year plus), she sat by my side and we greeted, I joked a little with her baby and things got even.

So the driver got to a junction where a passenger would alight and also carry more pple standing at the roadside but heading the same way the bus was heading.

while things were in progress, the conductor was busy screaming YABA! YABA!! YABA!!! then suddenly lol, the same baby started screaming along side with the conductor... Screaming YABA YABA YABA.... I couldn't help it as I burster into laughter including the other passengers on board ...the baby's mom was also laughing as the baby continued to scream YABA! YABA!! YABA!!! along side with the conductor... It was so damn funny to everyone till the baby's mom didn't find it funny any more and covered the baby's mouth lol

Most babies learn by imitation these days. Funny sha

Yes, that's the age "learning by imitation ". My 22months old will repeat words for words and actions for actions. In fact he would hit grandma with a tiny cane reserved for him and say "egba".
We should thus try to live as rightly as possible while raising them, cos take everything in hook, line and sinker
