very troublesome but no big mistake wor ... keep a tight eye on her on $$$ and see if she can handle your BB well la ... however, if you have another good choice, fire her la since a new BB will consume all your energy ga!!
If I were you I would fire her and employ a younger one and never come to HK before. Yours is too old to look after new born. And one who have never come to HK would be more obedient.
