Smart retorts from my 5-year old

Yiu Yiu doesn't like tofu and one day during dinner, I was feeding Yan Yan some steamed tofu and she happily lapped it all up, so I said:
Mummy: Yiu Yiu you see, mei-mei like tofu so much, you don't even want to eat.
Yiu Yiu: Haiya! You give mei-mei anything also she'll eat one la.

Yan Yan was crawling all over the bed trying to grab things at both bedside tables so I reprimanded her sternly, "Mei-mei, NO. Naughty!"
Yiu Yiu: Mei-mei naughty also you give birth to her one what.
Mummy: So it's my fault is it?
Yiu Yiu: No, your tummy's fault.

At kindy this year, Yiu Yiu has to do spelling, ejaan and 听写. She normally comes home with a small book with the words for ejaan or 听写 for the next week but I never realized what they were for until several weeks on. Inexperienced mummy :-) Anyway, after my realization, I started practicing with her. However for spelling, the children are not given the words in advance, as they are expected to be able to write them out simply by listening to the words (the kindy used phonics to teach English). She always come back with lots of mistakes, sometimes not even one correct. When I asked her, "How come you don't know the words? So many mistakes." She retorted, "You la, teacher say must practice the Blend Book at home. You never practice with me also."

OUCH!!! Yiu Yiu – 3, mummy – 0.
