Being a parents is the greatest gift from God. Any kind of behavior of the babies make us that those are miracle. Anything happened and there are always changes on them, either physicaly or mentally. All of their motions are something that we would not ever disobeying them. We always take care and pay attention for them, for any changes on them.
Yet, do you ever take care why the baby's first words are often 'mama' and 'papa'. When we hear those words spoken by our babies, the great happiness got increased in our heart. Then, this seems so natural for us that we hardly think why babies actually utter these words first. 
Untill, the experts at the University of British Columbia have made brain scans of babies to successfully crack that mystery. The secret lies in repeating the same syllables. The study involved newborns (age 2 days to 3 days). When babies heard repeating syllables, their brain activity increased in the zones responsible for attention, abstract thinking, hearing and speech functions. Figuratively speaking, more complex words go in one ear and out the other, causing no responses from the baby’s brain. Conducted experiments convincingly explain why babies around the world speak nearly the same language. Mama, papa, dada are the most simple words for them to understand and to utter.
