Kendra Teo Jia Ning

Normally when I asked Kendra who is she, she will either answer me "kendra", "ying ying" or "girl girl". I'm so surprise with her answer when I ask her the same question this morning. Here is our conversation:

me: hey, who are you?
Kendra: annnn...dra (kendra)
me: No, again who are you?
Kendra: ying ying
me: NO......
Kendra: girl girl
me: No No
Kendra: annn dra jia ning
me: huh...again, what is your name?
Kendra: annn dra jia ning (kendra Jia Ning, her surname was missing)

Now only I realized that she know her full name. It must be teach by her nanny. Hopefully I can hear her spell out her name soon.
