Sky's current favourite word is "NO". This is all too familiar for me as Shannon went thru this stage before. Today, our helper related a funny incident to me.

Aunty: Sky! Eat your lunch now.
Sky: No No...Wait...later
Aunty (pleasantly surprised that Sky can string words together) : who teach you to say later?
Sky: Jie Jie

Obviously, wrong things are learnt fast.
