Cousin's visit

Was trying to recall when one of my nephew visited us today. Cousin #1 saw CM and said, "Baby, open mouth, show teeth" while showing his own set of teeth to CM... We were laughing out loud! That was soooo cute... but where did he get that idea?? a two year old toddler!!!

Baby / Toddlers' mind are programmed. Its like GIGO (Garbage in, Garbage out). What ever comes out from their mouth are actually copied from parents or people around them....

Makes me worried, would CM cope it as he gets older?
