My son just walk alone on last Thursday. Papa and I were very excited. He will wave hand to show "Hi Hi" and "Bye Bye" but still hasn't started to talk not even say "papa" or "mama". he is still speaking BB language.
He used to know to 請請 but in the past 4 months he refuse to do so. I teach him to "請請" since then but still doesn't do 請請......
