He's getting more vocal

Hihi... din blog for some time again. Just to add on his latest development in case i forgot about it. he's getting more vocal and can use his tone to show whether he's happy or frustrated. he knows more words now and is starting to use them in his communication with us. he can also end the last word of each line in 'twinkle twinkle little star' and can complete some number patterns such as '1,2...' and he will say '3'. however, there are also times when he refused to say anything at all. he seemed to be more interested in numbers than in languages. prefers dvds that shows counting or related to numbers. seems like he'll be different from his mum. haha... i can never do well in maths.
