Pushing the limits

This two weeks Richie has been pushing the limits, our patience to be exact.
Whenever mommy told him not to do, he will do, if mommy asks him to do something, he won't do it.
It really drives mommy crazy. Mommy's not sure why he's behaving like that suddenly from being good boy.
Hopefully it's just phasing stage...

But so far he likes to go to class, the weekly chinese class, he's looking forward to meeting his laoshi.
The good feedback from laoshi, he's actively participating now, even when he's back home, he could sing the song, not sure its title though hehe...
