Buggy or Piggyback?

I saw a funny sight today in town. A Nigerian woman all dressed up for the winter, I mean coat, boots and scarf and the weird thing?  she had her baby tied to her back with a colorful african wrapper. I could hear her husband complaining about the fact that he bought a buggy which she wanted at the time but is now sitting somewhere in the house gathering dust. The lady's response ? "the buggy is heavy"!

i think her husband was quite embarrased by the sight they made in the busy town centre. What do you think people?  would you as an African woman carry your baby on your back in public? and would you as an african man be seen in public with your wife carrying your child on her back?
