Little Happy was already one year old, but he always babbled and did not call out 'Father and Mother'. A few days ago, on his first birthday, he caught hold of a small abacus and began to babble and dance, happily showing off to his mother. However, he still did not call her mother.

If it was a child that spoke earlier, he would have been able to call out 'father' and 'mother' by now
