Mei Mei likes to go to the garden to play, so I ask her if you want to go out, said walk walk. If she follow then only I let her out. Since then, whenever she want to go out, she'll point to her shoes and say walk walk. hehe.. I did it, although is just a word.
Another milestones that I hope she can reach is she can express herself by words, speak more by her own free will, not by instructions.

Words she can say:
walk walk，papa, mama, kakak, jie jie (not really pronounce clearly).
