Lina,
we did the same thing with Mika oso...
after every punishment, mesti ada interaction moment. we asked him dia tau tak knaper dia kena punish, blah blah....
and we explain nicely....
kadang, ada baiknya budak2 maid jaga, coz at least dorang sebumbung....
diff caregiver = diff way of upbringing.
if tak clash takper... but most of the time, budak2 jadi confuse...
