if you don't want to put your beloved children at risk, sent her back home lah!
she is not only "unexperienced"; she is doing work half-half with no heart at all ! and only "pretend" to be stupid. they are actually very smart , smart in the way to be lazy and dis-honest.
to me, I 'd rather hire one maid who is not good at housework and not good at cooking but with true love&care to take care of bb/child and honest to me.
for your reference only. i also understand how bad you feel, just hire 3 month but the maid is so bad.......
