Let me introduce you to Kiki. He's my 15 months old who still communicate in his 'babyish' language. Unlike the other two kiddos that mastered quite well with understandable language at that age, Kiki's first word, unfortunately is not 'mama'. The first vocab that came out from his mouth is 'Nak' and that means 'I want'.
After a month plus of 'Nak', he now advanced to his second word which is 'Butak'. He started using it for the first time when i carried him from his daycare and when his hand started to pull at my shirt. Aaahhhh...then I realized that he's looking for the boobs - his food. So, from then onwards, feeding time means Butak time.
Can't hardly wait for his third vocab ...what would it be, ehh???
